How to declare 64bit integer
i know i need to do
but i get an error saying 'long' followed by 'long' is illegal"
unsigned long long int numb;
i have an amd 64 bit cpu, but i am still using 32 bit windows.
i use visual c 6.0 to write my program(homework).
please help. appreciate it. :tntworth:

I've no idea whether your old compiler even understands __int64 as a type, but even if it does, it's not likely to be generating 64-bit instructions to take full advantage of your processor.
