打开VC++6.0，点击工具栏上的“新建”图标建立一个空白文档（注意不是点击菜单File―New），把以下代码复制进去：
#include
#include
void main()
{
int m,i,s=0;
printf("2~1000的数中：\n");
for(m=2;m<=1000;m++)
{
for (i=1;i
if(m%i==0)
s=s+i;
}
if(s==m)
{
printf("%d为一衡配个完数,因子为",m);
for(i=1;i
if(m%i==0)
printf("%d,",i);
}
printf("\n");
}
s=0;
}
}
点击“编译”，弹出的对话框选择“是”（将为你自动建立一个工程），咐厅指将文件名改为“Text1.c”，选择伏巧一个工程的存放位置，点击“保存”。然后编译运行即可。
不知道你还有没有特殊要求，比如想要基于MFC而不仅仅是基于VC环境？
你把下边这个程序改改就是你要的
