# include <stdio.h>
void swap(int *a, int *b)
{
*a ^= *b ^= *a ^= *b;
}
int main()
{
int a=45, b= 56;
// a ^= b ^= a ^= b;
swap(&a,&b);
printf("%d %d",a,b);
}
This code gives output 0, 45
While if we uncomment the line in main function and don't use swap
function, we get correct value. Explain why the same line when used in
swap function gives such output.
