Geeksforgeeks C: Programming

int main() int x = 5, y = 10; swap(&x, &y); printf("x = %d, y = %d", x, y); // x = 10, y = 5 return 0;

#include <stdio.h> void swap(int *a, int *b) *a = *a + *b; *b = *a - *b; *a = *a - *b;

This works but risks overflow. Alternative using XOR:

Introduction C programming remains the cornerstone of modern software development. From operating systems to embedded devices, C's efficiency and control over system resources make it indispensable. GeeksforGeeks (GFG) has emerged as one of the most trusted platforms for learning C, offering thousands of examples, coding problems, and in-depth articles.
