How to display a 64-bit integer?
I'm trying to figure out how to write a function to print a 64-bit integer value.
Newer compilers have a built in 64-bit type, like in gcc its 'long long' and in Windows compilers its __int64. Anyway, I tried splitting it into 2 32-bit ints, but I can't figure out where to go from there. Any ideas?
by display it i mean print it in decimal form
in visual c++ for __int64 usesomething like
__int64 a=10;
char buff[256];
sprintf(buff, "%I64u", a);
............
and there you go, should you want to use cout, then overload the << operator for ostream with support for __int64, very simple.
