Literals In C/C++ With Examples

Literals in the C and C++ programming languages are fundamental building blocks that represent constant values directly in code. These constants can include integers, floating-point numbers, characters, and more. Literals are essential for initializing variables, specifying values in expressions, and conveying data directly within the source code. They provide a means to express concrete values without requiring variables or complex computations. In this exploration of literals in C/C++, we will delve into the various types of literals and provide illustrative examples to demonstrate their usage and significance in these programming languages.

Literals In C/C++

Literals in programming, whether in C or C++, are indeed constant values assigned to variables that remain fixed and unmodifiable throughout the program’s execution. Unlike variables, literals are not associated with references and directly hold their values in memory. In common usage, the terms “constants” and “literals” are often used interchangeably.

For instance, consider the expression “const int x = 5;,” where the value 5 is a constant integer literal. In the world of C, there are four primary types of literals, while in C++, there are five:

1. Integer Literal: Used to represent whole numbers, such as 42.
2. Float Literal: Represents decimal numbers with a fractional part, like 3.14.
3. Character Literal: Represents a single character enclosed in single quotes, such as 'A'.
4. String Literal: Represents a sequence of characters enclosed in double quotes, like "Hello, World!".
5. Boolean Literal (C++): Represents either true or false, indicating logical values in C++.

These literals play a pivotal role in coding by providing a concise way to embed fixed values directly into the source code, enhancing readability and maintainability.

1.Integer Literals

Integer literals serve as a means to represent and store integer values in programming. They can be expressed in two primary types:

A) Prefixes: The use of prefixes with integer literals indicates the base or radix in which the literal is to be interpreted or read. These prefixes provide information about the numeric base of the integer value, which can be essential when working with numbers in different bases.

Example

0x10 = 16

Because 0x prefix represents a HexaDecimal base. So 10 in HexaDecimal is 16 in Decimal. Hence the value 16.

Integer Literals are of 2 types:

a. Decimal-literal(base 10)

It consists of a non-zero decimal digit followed by zero or more decimal digits, where decimal digits include the numbers 0 through 9. This is the common representation for integers in these programming languages, allowing you to express a wide range of positive integer values.

Example:

56, 78

 b. Octal-literal(base 8):

It begins with a ‘0’ (zero) followed by zero or more octal digits, where octal digits include the numbers 0 through 7. This representation allows you to specify integer values in octal base, which is base 8. Octal literals are less commonly used than decimal literals but can be useful in certain situations, especially when dealing with permissions and bit manipulation.

Example:

045, 076, 06210

d. Binary-literal(base 2)

It starts with either ‘0b’ or ‘0B’ followed by one or more binary digits, which are 0 and 1. This notation is used to represent integer values in binary base, which is base 2. Binary literals are valuable for expressing binary-encoded data or when working with low-level bit manipulation operations.

Example

0b101, 0B111

B) Suffix

Suffixes are added to the literal to specify its data type

Example

12345678901234LL 

indicates a long long integer value 12345678901234 because of the suffix LL

These are represented in many ways according to their data types.

• int: No suffix is required, as an integer constant is assigned as an int by default.
• unsigned int: Append ‘u’ or ‘U’ at the end of an integer constant.
• long int: Add ‘l’ or ‘L’ at the end of an integer constant.
• unsigned long int: Include ‘ul’ or ‘UL’ at the end of an integer constant.
• long long int: Use ‘ll’ or ‘LL’ as a suffix for an integer constant.
• unsigned long long int: Employ ‘ull’ or ‘ULL’ as a suffix for an integer constant.

Example

#include <stdio.h>
  
int main()
{
  
    // constant integer literal
    const int intVal = 10;
  
    printf("Integer Literal:%d \n", intVal);
    return 0;
}

Output

Integer Literal:10

2) Floating-Point Literals

Floating-point literals are used to represent and store real numbers, which consist of an integer part, real part, fractional part, and exponential part. These literals can be represented in either decimal form or exponential form.

When creating floating-point literals, it’s essential to adhere to certain rules:

1. Decimal Form: If representing a floating-point number in decimal form, it should include the decimal point, exponent part, or both. Failing to include these components may result in an error.
2. Exponential Form: When using exponential form, ensure that it includes the integer part, fractional part, or both, as required. Omitting any of these parts can lead to an error.

Adhering to these guidelines helps maintain the accuracy and validity of floating-point literals, preventing potential errors in the code.

Floating-point literal representations are shown below:

Valid Floating Literals:

10.125
1.215-10L
10.5E-3

Invalid Floating Literals:

123E
1250f
0.e879

Example

#include <iostream>
using namespace std;
  
int main()
{
    // Real literal
    const float floatVal = 4.14;
  
    cout << "Floating-point literal: "
         << floatVal << "\n";
    return 0;
}

Output

Floating point literal: 4.14

3) Character Literal

Character literals are used to store a single character enclosed within single quotes (”). To store multiple characters, you would typically use a character array. Attempting to store more than one character within single quotes results in a warning, and only the last character of the literal is considered.

There are two primary representations of character literals:

A. char Type: This representation is used to store normal character literals or narrow-character literals. It is supported by both C and C++. Character literals of this type can hold a single character within single quotes and are widely used in both languages.

Example:

// For C
char chr = 'G';

// For C++
char chr = 'G';

B. wchar_t type: Unlike the ‘char’ type, ‘wchar_t’ is used to represent wide-character literals and is supported only in C++. When a character is followed by the ‘L’ prefix, it indicates that the literal should be stored as a ‘wchar_t,’ representing a wide-character literal. This is particularly useful for dealing with wide characters and character sets that require a larger storage space than regular narrow characters.

// Not Supported For C

// For C++
wchar_t chr = L'G';

Example:

#include <stdio.h>
  
int main()
{
    // constant char literal
    const char charVal = 'A';
  
    printf("Character Literal: %c\n",
        charVal);
    return 0;
}

Output :

Character Literal: A

4) String Literals

String literals indeed serve as containers for multiple characters and are enclosed within double quotes (“”). Unlike character literals, string literals can store sequences of characters, making them suitable for representing text and longer data.

String literals can also handle special characters and escape sequences, which are denoted by backslashes, such as ‘\n’ for a newline or ‘\t’ for a tab. This flexibility allows you to include various characters and control codes within a string.

char greeting[] = "Hello, World!";

Example

#include <stdio.h>

int main() {
    // String literal
    char greeting[] = "Hello, World!";

    // Printing the string literal
    printf("Message: %s\n", greeting);

    return 0;
}

Output

Hello, World!

5) Boolean Literals

.Boolean literals are specific to C++ and are used to represent boolean data types. These literals can have two values:

1. true: This represents the “True” value and should not be considered equal to the integer 1, as it’s a distinct boolean value.
2. false: This represents the “False” value and should not be considered equal to the integer 0, as it’s a distinct boolean value.

Boolean literals are essential for writing clear and unambiguous code in C++ when working with boolean data types, making the code more expressive and readable.

// C++ program to show Boolean literals
  
#include <iostream>
using namespace std;
  
int main()
{
    const bool isTrue = true;
    const bool isFalse = false;
  
    cout << "isTrue? "
        << isTrue << "\n";
    cout << "isFalse? "
        << isFalse << "\n";
  
    return 0;
}

Output

isTrue? 1
isFalse? 0

Different Ways To Declare Variable As Constant In C And C++

Various Methods to Declare Variable Constant

There are various methods to make a variable constant.

1. Const keyword

One way is by using the const keyword. When you declare a variable with const, it means that its value cannot be changed once it’s set, and this is determined at compile time.

// C program to demonstrate const specifier
#include <stdio.h>
int main()
{
    const int num = 1;
  
    num = 5; // Modifying the value
    return 0;
}

When you declare a variable as const and then try to change its value, the compiler will generate an error similar to the one you mentioned: “error: assignment of read-only variable ‘num’.” This error is a safeguard to ensure that you don’t accidentally modify a constant variable.

2. Enum keyword

The enum keyword: is used to define an enumeration in C and C++. Enumerations allow you to assign names or labels to integral constants, making the code more readable and maintainable. Here’s an example of how you might use enum in C++:

// In C and C++ internally the default
// type of 'var' is int
enum VARS { var = 42 };
  
// In C++ 11 (can have any integral type):
enum : type { var = 42; }
  
// where mytype = int, char, long etc.
// but it can't be float, double or
// user defined data type

3. Using constexpr keyword

In C++, the constexpr keyword is used to declare variables as guaranteed constants. When you declare a variable, it must be initialized with a constant expression. This means that the value must be computable at compile time, not runtime. If the initializer of a constexpr variable isn’t a constant expression, the code will fail to compile. This helps ensure that constexpr variables are indeed constants that can be determined at compile time for optimization purposes.

#include <iostream>
  
int main()
{
    int var = 5;
    constexpr int k = var;
    std::cout << k;
    return 0;
}

If you attempt to initialize a constexpr variable with a value that cannot be determined at compile time, you will receive an error message like the one you mentioned: “error: the value of ‘var’ is not usable in a constant expression.” This is a compiler error designed to enforce the rule that constexpr variables must be initialized with constant expressions.

If you want a variable to be a true constant, which means its value cannot be changed after initialization, you should declare it using the const keyword.

4. Using Macros

Macros can be used to define constants in C and C++. However, there are some important considerations and potential issues when using macros for constants.

Macros in C and C++ are handled by the preprocessor, and they perform simple text replacement in your source code before it’s compiled. This text-based substitution means that macros lack type checking, and they can indeed be redefined or changed throughout your codebase, leading to potential errors and unexpected behavior.

// C++ program to demonstrate the problems
// in 'Macros'
#include <iostream>
using namespace std;
  
#define var 5
int main() {
    printf("%d ", var);
  
    #ifdef var
    #undef var
  
    // redefine var as 10
    #define var 10
    #endif
  
    printf("%d", var);
    return 0;
}

Output

Output: 5 10

Note :

1. Preprocessor Macros: Preprocessor macros are essentially text replacements and are suitable for defining literal constants. They are not associated with any specific data type or memory location. They are primarily used for simple text substitution and should be avoided for more complex constant requirements.
2. Enums: Enums provide symbolic names for integral constants and are suitable for defining integer constants. Enums do not have specific memory addresses and are typically used for making code more readable and maintainable.
3. const and constexpr: const and constexpr are used to define true constants with specific memory addresses. They provide type safety and are the recommended way to define constants when you need them to have a particular data type and memory location. const is used for runtime constants, while constexpr is used for compile-time constants.

In practice, const and constexpr are preferred for defining constants when you need type safety, memory control, and more versatile constant values. Preprocessor macros and enums have their use cases but may not offer the same level of control and safety as const and constexpr.

How To Install C++

If you want to start using C++ on your laptop, you’re in the right place. C++ is a programming language used for creating all sorts of software. Whether you’re new to programming or already experienced, this guide will help you easily install C++ on your laptop. When you’re done, your laptop will be ready for C++ programming, and you can begin your coding adventure.

What is C ++

C++ is a versatile programming language known for its unique characteristics. It’s a language that’s statically typed, meaning you need to declare variable types before using them. It’s compiled, which means the code is translated into machine-readable instructions before execution. C++ is a general-purpose language, so it can be used for a wide range of applications.

One interesting thing about C++ is that it’s case-sensitive, so capitalization matters in your code. It supports various programming paradigms like procedural, object-oriented, and generic programming.

C++ was created by Bjarne Stroustrup back in 1979 at Bell Labs. It started as an improvement to the C language and was initially called “C with Classes.” However, in 1983, it got its current name, C++.

An important thing to note is that C++ is a superset of C. This means that almost any valid C program can also be a valid C++ program. This feature allows for easy migration and compatibility between the two languages.

Object-Oriented Programming

C++ is a programming language that offers robust support for object-oriented programming, encompassing the essential principles known as the four pillars of object-oriented development:

1. Encapsulation: C++ allows you to encapsulate or wrap data and the methods that operate on that data into a single unit called a class. This promotes data security and prevents unauthorized access or modification of data.
2. Data Hiding: With C++, you can hide the internal implementation details of a class and expose only the necessary interfaces or public methods. This concept, known as data hiding, ensures that the complexity of the class is hidden from users, promoting simplicity and ease of use.
3. Inheritance: C++ supports inheritance, allowing you to create new classes (derived or child classes) based on existing classes (base or parent classes). Inheritance enables code reuse and the establishment of relationships between classes, making it a powerful feature for building complex software systems.
4. Polymorphism: Polymorphism in C++ allows objects of different classes to be treated as objects of a common base class. This facilitates flexibility and extensibility in your code, as you can create functions and methods that work with objects of multiple derived classes without knowing their specific types.

These four pillars are fundamental concepts in object-oriented programming and are essential for building modular, maintainable, and scalable software systems using C++.

The ANSI Standard

The ANSI (American National Standards Institute) standard for C++ serves a crucial purpose in the world of programming. It aims to guarantee the portability of C++ code across various platforms and compilers. This means that code you write for one specific compiler, such as Microsoft’s, should be able to compile without issues when using a different compiler on various systems, including Mac, UNIX, Windows, or Alpha.

The ANSI standard has remained consistent and unchanging for a significant period. Additionally, it has gained widespread acceptance and adoption in the programming community. As a result, all major C++ compiler manufacturers have aligned their implementations with the ANSI standard. This ensures that developers can write C++ code with confidence, knowing that it should work consistently across different environments and compiler brands. This portability is a valuable feature of the language, promoting code reuse and reducing platform-specific issues.

Learning C++

When learning C++, it’s essential to focus on understanding the basic concepts. The main goal of learning a programming language like C++ is to become a better programmer. This means getting better at designing and building new systems, as well as maintaining existing ones.

C++ allows you to code in different styles, like Fortran, C, Smalltalk, or others. Each style can be effective and efficient in terms of how it uses computer resources. This flexibility lets you choose the coding style that works best for your projects and preferences.

Advantages Of C++

• C++ is a widely adopted programming language, with a vast community of programmers using it across various application areas.
• It finds extensive use in tasks that involve writing device drivers and software requiring direct interaction with hardware while adhering to real-time constraints.
• C++ is also a popular choice for educational and research purposes because it offers a clean and understandable syntax, making it suitable for teaching fundamental programming concepts effectively.

If you’ve ever used an Apple Macintosh or a Windows PC, you’ve indirectly interacted with C++. This is because the core components of these systems, including their user interfaces, are built using C++.

Steps To Download C++

To get started with C++ programming, you’ll need a C++ compiler. There are several compilers available, and one option is Turbo C++. Here are the steps to install Turbo C++:

1. Download Turbo C++: First, download the Turbo C++ software from a trusted source.
2. Create a Directory: Create a directory called “turboc” inside your C drive (usually C:).
3. Extract Files: Extract the contents of the downloaded tc3.zip file into the “C:\turboc” directory.
4. Run the Installation: Locate and double-click on the “install.exe” file within the “C:\turboc” directory to start the installation process.

>cls 

Linux users

• Linux also has a command ” clear screen” in Python easily, so use the following command to do it.
• $ clear

Using Click Library

Use the click library to create a function that functions on both Windows and Linux.

Code

# Python program to clear screen using click.clear() function

# Import click library

import click

def clrscr()

# Clear screen using click.clear() function

click.clear()

print(“Screen Cleared”)

clrscr()

Output

Screen Cleared

Code Explanation:

Here in this example, click. clear() function from click library to clear screen. This function works in Windows, Linux, and Mac operating systems.

Using \n (Newline character)

There’s a different way to clear the screen, without running an external process. To do this, you can print several new lines (“\n”) to create a clear screen effect.

Code

# Python program to clear the screen using \n

# ‘\n’ is a newline character

def clrscr():

# Print ‘\n’ 10 times

print (“\n” * 10)

print(“Screen Cleared”)

clrscr()

# Python program to clear the screen using os.system

# Import os module

import os

def clrscr()

: # Check if Operating System is Mac and Linux or Windows

if os.name == ‘posix’:

_ = os.system(‘clear’)

else:

# Else Operating System is Windows (os.name = not)

_ = os.system(‘cls’)

print(“Screen Cleared”)

clrscr()

Output

Screen Cleared

Code Explanation:

After applying the syntax above, the output displays “Screen Cleared.”

In the initial example, we check the operating system using the os. name method. If it’s Linux or Mac (os.name = “posix”), we execute os. system(‘clear’). Otherwise, for other systems, we use os.system(‘cls’).

Using Subprocess Library

In this example, we have used the subprocess() function to execute an action for clearing the screen in output.

Input

# Python program to clear the screen using subprocess.call() function

# Import subprocess library

import subprocess

def clrscr():

cls = subprocess.call(‘cls’,shell=True)

print(“Screen Cleared”)

clrscr()

Output

Screen Cleared

Conclusion

Numerous ways exist to clear the Python screen without errors. However, using the click library is remarkably simple and versatile. It smoothly operates on Unix, Windows, and macOS, eliminating the need for OS checks.

What Is The Difference Between Binary Search And Linear Search?

Welcome to our exploration of two fundamental search algorithms: binary search and linear search. In the realm of computer science and programming, these techniques play pivotal roles in efficiently locating specific elements within a collection of data. Whether you are an aspiring programmer, a curious enthusiast, or a seasoned developer seeking a refresher, this article will delve into the key distinctions and inner workings of binary search and linear search.

Join us as we embark on a journey to unravel the mysteries behind these search algorithms and discover when and how to best utilize them in solving real-world problems. Let’s dive in and understand the fundamental differences between these two essential methods of data retrieval.

Linear Search

Linear search, also called sequential search, is a way to find something in a random list of stuff. You start from the beginning and check each item one by one. If you find what you’re looking for, you tell the position. If not, you keep going until the end of the list. If you still can’t find it, you say “Sorry, I couldn’t find it” by returning -1. It’s a simple method, but it can take a while for large lists or if the thing you want is far down the list. There are smarter ways to find things faster, but this is the basic one.

Code Syntax for the Linear Search.

Binary Search

In binary search, we use a smarter way to find something in a sorted list. Instead of checking each item one by one like in linear search, we start by looking at the middle item of the list. If the middle item is what we’re looking for, great, we’re done! But if it’s not, we know whether the item we want is in the first half or the second half of the list.

So, we cut down our search to half right away. If the middle item is greater than what we’re looking for, we know the item we want must be in the first half of the list. Otherwise, it must be in the second half. Hence, Binary search is more efficient than linear search, especially for large sorted lists, because it eliminates half of the remaining search space at each step, searching faster.

Code Syntax for the Binary Search

Main Difference Of Linear Search and Binary Search

Conclusion

Linear search is simple and works with any type of list, whether it’s sorted or not. It checks each item one by one, starting from the beginning, until it finds the target item or reaches the end of the list. While easy to understand, it may be slow for large lists, especially if the item is far down the list.

On the other hand, binary search is more efficient, but it requires the list to be sorted. It starts by checking the middle item and narrows down the search to half the list based on whether the target item is greater or smaller than the middle. It keeps repeating this process, cutting down the search space in half with each step, until it finds the target or can’t narrow it down further. Binary search is ideal for large sorted lists, as it quickly finds the target item.

In summary, use linear search for small or unsorted lists, and binary search for large sorted lists when you need faster results. Each method has its strengths, and understanding their differences helps you choose the right approach for your specific problem.
