What are procedures and How we use procedures.

 What are procedures in programming?

 

Procedures, also known as subroutines or functions, are blocks of code in a program that perform a specific task. They are designed to be reusable, so that the same task can be performed multiple times without having to write the same code over and over again. Procedures can take input, called arguments, and they can also return output, called a return value. They are commonly used to organise and modularise code, making it easier to read, understand, and maintain.

 

Types of procedures:

 

There are several types of procedures in programming, including:

 

1.     Subroutines: Also known as "procedures," these are blocks of code that perform a specific task and do not return a value.

2.     Functions: Similar to subroutines, functions are blocks of code that perform a specific task. However, they do return a value.

3.     Constructors: These are special types of procedures that are used to create and initialise objects in object-oriented programming languages.

4.     Destructors: These are special types of procedures that are used to clean up and deallocate objects in object-oriented programming languages.

5.     Methods: In object-oriented programming, methods are procedures that are associated with a specific object or class. They can be used to perform actions on or retrieve information about the object.

6.     Event handlers: These are procedures that are executed in response to a specific event, such as a user clicking a button or a network connection being established.

7.     Anonymous functions: These are procedures that are defined and executed without a name. They are often used as arguments to other functions, such as callbacks and higher-order functions.

 

Uses of procedures:

 

Procedures are used for a variety of reasons in programming, including:

 

1.     Code organisation: Procedures help to organise and modularise code, making it easier to read, understand, and maintain.

2.     Reusability: Procedures can be used multiple times within a program, reducing the need to write the same code multiple times.

3.     Abstraction: Procedures can be used to abstract away complex or repetitive tasks, making the code that calls the procedure simpler and more readable.

4.     Debugging and testing: Procedures can be tested and debugged individually, making it easier to identify and fix errors in the code.

5.     Concurrent execution: Procedures can be executed simultaneously, allowing the program to perform multiple tasks at the same time, making the program more efficient.

6.     Abstraction of data: Procedures can be used to hide the internal details of how data is stored and processed, making the code that uses the data simpler and more readable.

7.     Event-driven programming: Procedures can be used to respond to certain events, such as user input, network connections, and timers.

8.     Higher-order functions: Procedures can be passed as arguments to other procedures and returned as a value, allowing for more expressive and powerful code.

 

Those are procedures and types of procedures and uses.

  Starting with FreeCodeCamp                 The last week I sign up with FreeCodeCamp. here is some information about freeCodeCamp. I will share my experience with freeCodeCamp. FreeCodeCamp is a non-profit organization that offers free, self-paced, online courses in web development and data science. It was founded in 2014 by Quincy Larson with the goal of providing accessible education for anyone who wants to learn to code. The curriculum of FreeCodeCamp is based on hands-on coding projects that teach students the practical skills they need to become job-ready developers. The courses are designed to be completed in approximately 300 hours, with each module building on the skills learned in the previous one.   FreeCodeCamp's web development curriculum includes HTML, CSS, JavaScript, React, Node.js, and more. The data science curriculum covers topics like data analysis, visualization, and machine learning. One of the unique features of FreeCodeCamp is its emphasis on

Stop Wasting Time and Start 5 EASY PROGRAMMING LANGUAGES!

  What are easy programming languages?   There is no one "easy" programming language that is best for everyone, as the concept of "easy" can be highly subjective and dependent on an individual's background, goals, and interests. Some programming languages are generally considered to be easier to learn and use than others, however.           Here are a few programming languages that are often recommended for beginners:   1.       1.         Python : Python is a high-level, interpreted language with a simple syntax and a large standard library. It is a good choice for beginners because it is easy to read and understand, and it has a large and active community of users who can provide support and resources.   2.        Scratch : Scratch is a block-based programming language developed by MIT specifically for beginners. It is designed to be easy to use and is often used to teach young children how to program.     3.        HTML and CSS : HTML (HyperText

What Everyone Must Know About WHAT ARE CONDITIONAL STATEMENTS?

   What are conditional statements? A conditional statement in programming is a control flow construct that allows code execution based on the evaluation of one or more conditions. It checks if a certain condition is true, and if it is, a specific block of code is executed. The syntax for a conditional statement often looks like this: Example code: if (condition) {   // code to be executed if the condition is true } else {   // code to be executed if condition is false }                     The "else" part is optional, and multiple conditions can be tested using if-else if constructs. Conditional statements are an essential part of almost every programming language and are used to make decisions in code. There are several types of conditional statements in programming:   if statement: It executes a block of code if a specified condition is true. if-else statement: It executes a block of code if a condit
