#include stdio.h
#include string.h
void swap(int*, int *);
void main()
{
int num1, num2;
printf("\nEnter two numbers:");
scanf("%d %d", &num1, &num2);
printf("\nThe numbers before swapping are Number1= %d Number2 = %d", num1, num2);
swap(&num1, &num2); /* Call by Reference to function swap */
printf("\nThe numbers after swapping are Number1= %d Number2 = %d", num1, num2);
}
void swap(int *x, int *y)
{
*x = *x ^ *y;
*y = *x ^ *y;
*x = *x ^ *y;
}
