Answer / adarsh jain
We can do it using pointers easily...
See the code snippets below..
#include<stdio.h>
void swap(int *a, int *b);
int main()
{
int a = 10;
int b = 20;
swap(&a, &b);
return 0;
}
void swap(int *a, int *b)
{
printf("Before swapping , a = %d, b = %d\n", *a ,
*b);
*(a+1) = *a;
*a = *b;
*b = *(a+1);
printf("After Swapping, a = %d, b = %d\n", *a, *b);
}
