As per c99 standard, size of long long should be minimum 64 bits. How is this implemented in a 32 bit machine (eg. addition or multiplication of 2 long longs). Also, What is the equivalent of long long in C++.
On the IA32 architecture, 64-bit integer are implemented in using two 32-bit registers (eax and edx).
There are platform specific equivalents for C++, and you can use the stdint.h header where available (boost provides you with one).
