What is C Language?

C is a general-purpose programming language created by Dennis Ritchie in 1972 at Bell Labs. It is known for high performance, efficient execution, and close interaction with system memory and hardware. C follows a structured programming style that helps you write clear, organized, and maintainable code while building a strong understanding of how programs work internally.

It is used to build operating systems, embedded software, and device drivers. Many modern languages are influenced by C, making it a strong foundation for learning programming and software development today.

C Code Example 

#include <stdio.h>

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