@Shivam: Your one-line "solution" violates the sequence point rule. Hence,
it is non-standard, and the result is compiler dependent.

+1 umer ..
question is to swap for objects ..
how do u define '+' on objects(which may contain any type, even dynamic
memory allocation).

yep its right.one mre method will be
a=a+b;
b=a-b;
a=a-b;

XOR option wont work for floating points so being generic, using temp
variable is the best option for swapping.
Anyways, the question requirement was to swap without temp, hence above
given solutions go right.

a=a^b;
b=a^b;
a=a^b;
need to check if a and b are equal or not , bcozz a^a =0

Swapping two objects (not integers/chars),without using temp...?
my solution is using xor operation..is that right and ny other solutions ?
