}

再就是新建一个程序，作为启动的进程程序：Testor

这个程序的Testor.exe文件将影响到上面启动进程的路径。 Testor.cpp:

#include <iostream>

using namespace std;

int ChangeNum = 0;        //全局变量

int main()
{
    int insideNum = 200;        //局部变量
    ChangeNum = 1600;

    while (true)
    {
        printf(" insideNum = %d, addr = %X; ChangeNum = %d, addr = %X \n",
            ++insideNum, &insideNum, ++ChangeNum, &ChangeNum);
        getchar();
    }
    return 0;
}
