Program to check process architecture

Here is a small command line program written in C++ to check whether executable process architecture is 64 bit or 32 bit.

// IS64.cpp : Defines the entry point for the console application.

#include <iostream>
#include <vector>
#ifndef countof
#define countof(_Array) (sizeof(_Array) / sizeof(_Array[0]))
#endif
