C++ does not have built-in support for big integers. You need to create routines yourself or find routines written by someone else.

I'm curious, what syntax did you try, the one in Java?

Thanks for that!!! I got the point now actually i read many times on this forum that there is a need to use bigint..... and by this i thought that like java we have something in c++..... actually i m a newcomer to c++..... so i got error while trying it and than i thought to enquire about that....

but still i m not very much sure about using this concept ..... if u can somehow give me an example reference.... i think i will get it better!!!

Thanks a lot!!!!!
Trying to learn!!!

The only example reference I remember off the top of my head is this:

http://www.shygypsy.com/tools/BigInt.cpp

But you could try googling also. Others probably exist.

WOW, this file ROCKS! Although it said there are still some bugs, but I think it would be a good start if you try to implement your own Bigint library. :D
Have you ever...
  • Wanted to work at best companies?
  • Struggled with interview problems that could be solved in 15 minutes?
  • Wished you could study real-world problems?
If so, you need to read Elements of Programming Interviews.
