拥有构建良好的简单控制台应用程序：

#include "stdafx.h"
int _tmain(int argc, _TCHAR* argv[])
{
    return 0;
}

#include <cstring>如果我添加行（或（和）#include <string>），它也会构建得很好

#include <cstring>
#include "stdafx.h"

int _tmain(int argc, _TCHAR* argv[])
{
    return 0;
}

如果我gc.c只添加一个包含行的文件，#include <cstring>（或（和）#include <string>），编译器会产生很多错误：

看起来编译器不理解包含中存在的任何内容。

包含<cstring>或<string>附加 cpp 文件有什么问题？

并且总是习惯于包含这样的文件

#include "stdafx.h"    //Always include it first then other files.
#include <cstring>
