Swapping example in C:

Swapping:

#include
int main() { 

int a, b, temp;

 printf("Enter the value of a and b: \n");

 scanf("%d %d", &a, &b); 

 printf("Before swapping a=%d, b=%d \n", a, b);

 /*Swapping logic */

 temp = a;

 a = b;

 b = temp; 

printf("After swapping a=%d, b=%d", a, b);

 return 0;

 }

 Output:

 Enter the values of a and b: 2 3 

Before swapping a=2, b=3 

After swapping a=3, b=2
