Basic Structure of a C Program

Introduction

C programming is one of the most important languages for beginners.

Before writing any program, it is necessary to understand the basic structure of a C program.

Basic Structure of a C Program

A simple C program has the following parts:

Example of a Simple C Program

--------------------------------------------------

#include <stdio.h>

int main() {

printf("Hello, World!");

return 0;

}

--------------------------------------------------

Explanation of Each Part

1. Header File (#include <stdio.h>)

~It tells the compiler to include standard input-output functions like printf().

2. Main Function (int main())

~Execution of every C program starts from the main() function.

3. Statements

~These are instructions given to the computer.

Example: printf("Hello, World!");

4. Return Statement (return 0;)

~It ends the program and returns control to the operating system.

*Why Understanding Structure Is Important:-

~Helps in writing error-free programs

~Makes debugging easier

~Essential for exams and real programming

Conclusion:-

Understanding the structure of a C program is the first step toward mastering C programming.

Once this concept is clear, learning advanced topics becomes much easier.
