variable sizes
Write your question here.
my problem is a very simple one. we all know that in c that we could initialize a variable like long long and the capacity of the new variable would be twice big than normal long variable. and in c++ this doesn't work. and the capacity of int and long are same. in this case how can I store something big in a variable please tell me.

About sizes:
int: at least 16 bit, usually 32 long: at least 32 bit, usually 32 on win machines and 64 on Linux long long: at least 64 bit |
Do not use doubles to store large integers, or you may run into precision issues when you do some operations.
