Or wait until 2014 when C++14 will be out. It should contain support for arbitrary size integers: http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2013/n3542.html

Numbers on a computer have a finite range. You really ought to look at how integers and floating point numbers are stored--it's as fundamental as knowing data structures, you just can program without knowing this stuff.

A bignum library allows larger integers to be stored. To a web search for bignum and you'll be presented with a few implmentations.
