CPP Programming Introduction

C programming language is a popular and widely used programming language for system-level programming, embedded systems, and game development. In this article, we will provide an introduction to C programming language with examples.

Hello, World! Program in C #

The “Hello, World!” program is a simple program that prints the text “Hello, World!” to the screen. Here is an example of how to write a “Hello, World!” program in C programming language

#include <stdio.h>

int main() {
   printf("Hello, World!\n");
   return 0;
}

In this example, we have used the printf function to print the text “Hello, World!” to the screen. The \n character is used to insert a new line after the text.

Basic Syntax #

C programming language has a simple and straightforward syntax. Here are some key elements of the syntax

Comments #

Comments are used to add notes to your code. They start with /* and end with */. Here is an example of how to use comments in C programming language

/* This is a comment */

Variables #

Variables are used to store data. They are declared with a data type and a name. Here is an example of how to declare a variable in C programming language

int age;

Functions #

Functions are used to perform a specific task. They have a return type, a name, and parameters. Here is an example of how to define a function in C programming language

int add(int a, int b) {
   return a + b;
}

Statements #

Statements are used to perform an action. They end with a semicolon. Here is an example of how to use a statement in C programming language

printf("Hello, World!\n");

Compiling and Running C Programs #

To run a C program, you need to compile it first. Here is an example of how to compile and run a C program in command prompt

1. Save your C program with a .c extension, for example, hello.c.

2. Open the command prompt and navigate to the directory where your C program is saved.

3. Type the following command to compile the program

gcc -o hello hello.c

Type the following command to run the program

./hello

Conclusion #

In conclusion, C programming language is a powerful and versatile programming language that is widely used in the industry. By using the examples provided in this article, you can start learning how to write C programs. The “Hello, World!” program is a great place to start.
