P.S. Is there a way in C to declare an integer to be 64 bits long?

In C89: no, one should resort to OS/compiler specific code. In C99: yes (at least theoretically): #include <stdint.h> int64_t foo; However, a) be careful to not confuse it with intptr_t, b) beware of non-conforming compilers (in particular, the m$ one is particularly guilty). Best regards, Alexei P.S. Please use proper forums/mailing lists [1] for discussing generic questions about C/C++. Chances are that your question has already been answered.
