拼写没有错误

如果是缺少库可能是哪个呀?

我的包含
#include <windows.h>
#include <stdlib.h>
#include <string.h>

定义了
BOOL InitWindows(HINSTANCE hInstance,int nCmdShow);
在WinMain里有
if(!InitWindows(hInstance,nCmdShow))
return FALSE;

Compiling...
4.cpp
D:\graduate\程序\p10\4.cpp(14) : error C2065: 'nCmdShow' : undeclared identifier

这是全部的程序

麻烦懂的人给看看吧

请注意大小写

谢谢
就是这个问题……
