// address of num1 and num2 is passed to the swap function
swap( &num1, &num2);
printf("Number1 = %d ", num1);
printf("Number2 = %d", num2);
return 0;
}

void swap(int * n1, int * n2)
{
// pointer n1 and n2 points to the address of num1 and num2 respectively
int temp;
temp = *n1;
*n1 = *n2;
*n2 = temp;
