c=a+b
then find b=c-a;
if this b equals previous one then ok else overflow

regarding question related to overflow
int ovr_sum(int *sum,int a,int b)
{
*sum=a+b
if(*sum<0)
return -1; //overflow
else
return 0; //no problem with the sum (overflow don't occur)

generic swap can be written as -> #define Swap(T, a, b) {T temp = a; a=b;
b=temp;}
this is working fine in gcc

Thanks very much for recommending. By the way, Solutions to any problem
posted by anybody, will be available in some or other book. I also knows K&R
is a good book.

Q1 - write a generic macro to swap two values (int,float,double,pointers as
well )
Q2 - Implement your own malloc() and free() function
Q3 - Two unsigned ints given a, b you have add these numbers and return
the sum ...Make sure in case of overflow return "error".
