c. ORDER BY

d. SORT

Which SQL Keyword Is Used To Sort The Result-Set

Answer. Option B) Order By is the Correct Answer

In SQL, the ORDER BY the keyword is used to sort the result set of a query. You can use it to specify one or more columns by which you want to sort the rows in the result set, and you can also specify the sort order, which can be ascending (ASC) or descending (DESC).

Here’s the basic syntax of the ORDER BY clause:

SELECT column1, column2, ...
FROM table_name
ORDER BY column1 [ASC | DESC], column2 [ASC | DESC], ...;

• column1, column2, ... specifies the columns you want to retrieve in the result set.
• table_name is the name of the table from which you’re selecting data.
• ORDER BY is followed by one or more column names by which you want to sort the result set. You can also specify the sort order as ASC (ascending) or DESC (descending).

For example, if you want to retrieve records from a “employees” table and sort them by the “last_name” column in ascending order, you would use the following SQL query:

SELECT *
FROM employees
ORDER BY last_name ASC;

This would return the rows sorted by the “last_name” column in alphabetical order.

Difference Between Informed And Uninformed Search

Answer.

Informed and uninformed searches are two categories of algorithms used in computer science and artificial intelligence to find solutions to problems. The main difference between them lies in how they explore a search space and make decisions. Let’s explore these differences with examples:

1. Informed Search (Heuristic Search):

Informed search algorithms use additional information, often in the form of heuristics, to guide their search process. Heuristics are rules or estimates that provide information about how close a particular state is to the goal. These algorithms prioritize nodes that are more likely to lead to a solution based on this heuristic information.

Example: A* Search Algorithm

Consider a maze-solving problem where you have a maze and need to find the shortest path from the start point to the exit. In this case, an informed search algorithm like A* search can be used. A* utilizes a heuristic function that estimates the distance from each state to the goal. It then considers the sum of the actual cost to reach a state and the heuristic estimate. A* prioritizes expanding states that have lower estimated costs. This helps it efficiently find the shortest path through the maze.

2. Uninformed Search (Blind Search):

Uninformed search algorithms do not use any additional knowledge or heuristics about the problem domain. They explore the search space without considering how close a particular state is to the goal. These algorithms often have a systematic approach to exploration.

Example 1: Breadth-First Search (BFS)

Breadth-First Search is an example of an uninformed search algorithm. It explores the search space level by level, starting from the initial state and expanding all successor states before moving deeper. In a maze-solving scenario, BFS explores all possible paths systematically, ensuring that it finds the shortest path because it expands nodes in increasing order of their distance from the start.

Example 2: Depth-First Search (DFS)

Depth-First Search, another uninformed search algorithm, explores as deeply as possible along one branch of the search tree before backtracking. In the maze example, DFS may not guarantee finding the shortest path because it can explore deeply along one path before exploring other options.

In summary, the choice between informed and uninformed search depends on the problem and the available domain knowledge. Informed search algorithms are more efficient when you have relevant information, while uninformed searches are more suitable for situations where you lack such information or need to ensure completeness.

How to Choose an Instagram Username?

Selecting the right Instagram username is important because it represents your online identity. Here’s a step-by-step guide to help you choose the best Instagram username:

1. Reflect on Your Interests and Identity: Consider your hobbies, interests, and personality traits. Your username should reflect who you are and what you’re passionate about.
2. Keep it Simple: A username should be easy to remember and type. Avoid using complex spellings or special characters that might be confusing.
3. Be Creative: Try to come up with something unique and creative. Combine words, use puns, or create a portmanteau.
4. Relevance: If you’re using Instagram for a specific purpose (e.g., photography, fitness, cooking), make sure your username relates to that theme.
5. Avoid Trends: While trendy words or phrases might seem appealing now, they might not age well. Choose something that will still make sense in the future.
6. Check Availability: Before getting too attached to a username, make sure it’s available. Instagram usernames can’t have spaces, so you might need to use underscores or periods to separate words.
7. Short and Memorable: Short usernames are easier to remember. Aim for something that’s concise and leaves an impression.

9. Research Social Media Handles: Check if your desired username is available on other platforms as well. Consistency across social media can help with branding.
10. Test Pronunciation: Imagine saying your username out loud. Is it easy to say and understand? Avoid complicated spellings that could confuse people when spoken.
11. Think Long-Term: Choose a username that you won’t outgrow quickly. While something might be funny or relevant now, consider how it will hold up over time.
12. Personalize: If you’re comfortable, consider incorporating your name or a variation of it into your username. This adds a personal touch.
13. Ask for Opinions: Sometimes, a fresh perspective can help you see things you might have missed. Ask friends or family for their thoughts on your potential usernames.
14. Avoid Overused Words: Stay away from common words like “official,” “real,” or generic terms like “foodie” if you want your username to stand out.
15. Be Positive: Choose a username that radiates positivity and good vibes. This can attract more engagement and followers.

Remember, your Instagram username is an extension of your online presence. Take your time to find something that feels right and aligns with your goals for your Instagram account.

We’ll also see what skills they need and why they’re so important. As companies use blockchain to make things better and safer, they’re ready to pay these smart people well because they’re helping to make the way we do digital transactions and other things even better in the future.

What is the Blockchain Developer?

At the heart of blockchain technology is the blockchain developer. This specialist has a vital role in making and enhancing the rules for how blockchain works. This means they create systems where data can be both kept in one place or spread out. They’re also the ones who make smart contracts. In easier words, a Core Blockchain Developer prepares the foundation that others can use to build things. They deal with online apps that rely on blockchain. To put it simply, a blockchain developer is someone who helps make blockchain technology better.

What are the types of Blockchain Developers and their Roles?

In the realm of blockchain development, there exist two distinct categories of professionals:

1. Core Blockchain Developers
2. Blockchain Software Developers

A Core Blockchain Developer assumes the role of a decision-maker at a higher level. This involves tasks like establishing the fundamental structure of a blockchain system. They delve into determining the blueprint for protocols, crafting consensus mechanisms, and making pivotal choices related to blockchain. Their expertise requires a deep understanding of the inner workings of blockchain technology.

3. Cryptography: Just like in a secret agent movie, where they use secret codes to talk securely, blockchain developers use special codes to keep information safe. There are many types of these codes, like SHA256 and KECCAK256. It’s like having a special lock for your secret treasure chest.
4. Creating Smart Programs: Imagine if you could make your toys come alive and do cool stuff when certain things happen. That’s what a blockchain developer does with something called smart contracts. These are like mini-programs that can do things when certain conditions are met. They’re super handy for making sure things happen just the way they’re supposed to, without waiting or needing extra people.
5. Making Online Stuff: Being a blockchain developer means building cool things online. It’s like creating games or apps that work with blockchain. This involves both making things look good on the outside (front-end) and making them work well on the inside (back-end).

What are the Key Roles of Blockchain Developers?

A blockchain developer is like a digital security superhero. They set up special locks to keep bad guys out of the company’s important information. They also help build the technology and teach others how to use it. They work with other tech people to plan and design everything from the start.

The main tasks of a core blockchain developer include creating the main structure of the blockchain and making sure it’s safe. Here are some other things they do:

• Designing the way the blockchain looks and works.
• Figuring out how to keep everything safe and sound.
• Working together with other tech people to make sure everything is set up just right.

So, whether it’s building the foundation of a super cool digital system or making sure all the locks and codes are just perfect, being a blockchain developer is like being a tech wizard in a world of secret codes and digital adventures.

4. Cryptography Knowledge:
   Since security is a big deal in blockchain, you’ll need to understand cryptography. This includes encryption, decryption, and hashing techniques to protect sensitive data.
5. Smart Contract Development:
   Proficiency in developing smart contracts is vital, as they’re integral to blockchain applications. You’ll need to know how to write code that automatically executes when certain conditions are met.
6. Web Development Skills:
   Blockchain apps often have user interfaces that need to be designed and built. This requires front-end web development skills, including HTML, CSS, and Java
7. Continuous Learning:
   The field of blockchain is rapidly evolving. You’ll need to stay up-to-date with new technologies, updates, and trends.
8. Education and Training:
   While formal education is not always a strict requirement, having a background in computer science, software engineering, or a related field can provide a strong foundation. However, many developers also learn through online courses, tutorials, and hands-on experience.

What are the Salary of Blockchain Developers in India?

Due to a shortage of skilled individuals in the blockchain field, employers are ready to offer attractive salaries to professionals who prove their worth in this domain. The pay for a blockchain expert is significantly higher than that of an average IT professional. If you possess the right blockchain skills, you could earn double or even triple the annual salary of a Software Engineer.

As an increasing number of Indian companies and organizations jump on the blockchain trend, the average annual salary for a Blockchain Developer in India spans a wide range. Typically, the earnings of a Blockchain Developer in India can fall anywhere between Rs. 5,00,000 to Rs. 30,00,000 per year.

Moreover, the salary packages offered for roles in the field of blockchain are incredibly flexible. For example, an individual with approximately three years of experience in blockchain technology could earn an annual salary as substantial as Rs 45,00,000 or potentially even more. This amount is over twice the earnings of a professional with five years of work experience, albeit without any background in blockchain technology.

What are the Factors that Influence the Blockchain Developer’s Salary?

The income of blockchain engineers is influenced by several factors, including where they work, the company they work for, their years of experience, and their skills. The opportunities in this field are expanding rapidly, with growth rates ranging from 2000 to 6000 percent each year. Notably, in India, blockchain developers earn around 50 to 100 percent more than other types of developers.

The salary for blockchain developers in India can vary widely, spanning from Rs 5,00,000 to Rs 30,00,000 per year, depending on the various factors mentioned earlier.On average, a blockchain developer in India makes around Rs. 801,938 per year.

The skill set possessed by blockchain developers plays a significant role in determining their salary. A solid understanding of distributed systems and networking can be a considerable advantage.

Program Error Signals

Signals in computers enable communication between processes and the operating system. They’re triggered when a program encounters a critical error, signaling the OS to notify the process. Some processes have signal handlers for essential tasks before leaving the CPU. While signals and interrupts share similarities, interrupts are processor-generated and kernel-handled, whereas signals are kernel-generated and process-handled. Error signals often result in program termination, creating a “core” file for debugging, revealing the process state at termination.

Error Signals

• SIGFPE: Indicates an arithmetic error such as division by zero or a floating-point error. Storing integer data in a location used for a floating-point operation triggers an “invalid operation” exception.
• SIGILL: Denotes an illegal instruction, generated when executing a garbage instruction or one that a program lacks privileges to execute. In C, encountering this signal is unlikely unless the object file is corrupted. It’s also generated in the event of a stack overflow.
• SIGSEGV (Segmentation Violation): Occurs when a process attempts to access a memory location not allocated to it, often caused by de-referencing a wild pointer. It’s triggered when a program exceeds its memory space, detected by the memory protection mechanism.
• SIGBUS (Bus Error): Named for “Bus error,” this signal is generated when invalid memory is accessed. Unlike SIGSEGV, where the memory location exists but is invalid, SIGBUS occurs when de-referencing a memory location outside the allocated memory space.
• SIGABRT – If an error itself is detected by the program then this signal will generated using call to abort(). This signal is even used by the standard library to report an internal error. assert() function in c++ also uses abort() to generate this signal.
  

// Example of 'SIGABRT' error
 
#include <iostream>
using namespace std;
 
int main() {
 
    int arr[5] = {1, 2, 3, 4, 5};
   
    // SIGABRT error
    arr[6] = 6;
   
    return 0;
}

Output

// Example of 'SIGABRT' error
 
#include <iostream>
using namespace std;
 
int main() {
 
    int arr[5] = {1, 2, 3, 4, 5};
   
    // SIGABRT error
    arr[6] = 6;
   
    return 0;
}

Output

Abort signal from abort(3) (SIGABRT)

• SIGSYS – 
  This signal will be sent to a process when there is an invalid argument is passed to a system call. 
   
• SIGTRAP – 
  This signal will be sent to process when an exception has occurred. This will be requested by the debugger to get informed. For example, if a variable changes its value then this will trigger it.

What Is The Return Type Of Getchar(), Fgetc() And Getc() ?

In C, when you use getchar(), fgetc(), or getc(), what you get back is not a character but an integer. So, it’s a good idea to catch that integer by using an integer-type variable. These functions return the ASCII value of the character you input or read, and using an integer-type variable helps you handle and check for special cases like the end of the file.

char ch;  /* May cause problems */  
while ((ch = getchar()) != EOF)  
{ 
   putchar(ch); 
} 

This version uses integer to compare the value of getchar().

int in;   
while ((in = getchar()) != EOF)  
{ 
   putchar(in); 
}
