INTRODUCTION

History and Features of C:
● C is a general-purpose programming language created by Dennis Ritchie at Bell Labs in the early 1970s.
● It is widely used for system programming, embedded systems, and application development.
● C became popular due to its efficiency, simplicity, and portability across different platforms.

Basic Structure of a C Program:
● A C program consists of functions, and it must have a main function, which serves as the entry point of the program.
● The main function contains the executable code of the program and returns an integer value to the operating system.

#include <stdio.h>
int main() {
printf(“Hello, World!\n”);
return 0;
}
