Mastering C Programming

C is a powerful and fast language developed in the 1970s. It remains the foundation of operating systems and high-performance software today.

2. Basic Program Structure

A standard C program includes headers and a main() function.

#include <stdio.h>

int main() {
    printf("Hello C Programming!");
    return 0;
}

Pointers store memory addresses, giving you direct control over hardware and memory allocation.

int num = 10;
int *ptr = # // ptr stores address of num

printf("Address: %p\n", ptr);
printf("Value: %d\n", *ptr);
