we need to use + and - as operator overloading. so, that i will work f9 for
ur objects.
so make operator overloading for + and - operator.

Can anyone please help me to understand (with example) that how those
solutions work, if they are OBJECTS?

@Don: This can be easily fixed, as there is no need to swap equal values,
so:
void swap(int a, int b)
{
if( a != b )
{
a ^= b;
b ^= a;
a ^= b;
}
}

Dave is right. The code is undefined, which means that a valid
compiler could produce code which makes monkeys fly out of your nose.

Note that most of these methods fail if you try to swap an item with
itself.
For example, swap(a[i], a[j]) will fail if i==j and swap is
implemented as
void swap(int a, intb)
{
a ^= b;
b ^= a;
a ^= b;
}

But how is that going to work for objects?

@Manish: Sure.

In 2-s complement arithmetic, it works even if a + b overflows.
