ld返回1退出状态 - Windows 8 x64

所以我正在组建一个程序来打印不同数据类型的二进制表示，当我编译时，我得到了这些错误

这是我的 Headers “display.h”

//          display.h

    Basic operations:

#include <iostream>

void printChar(char val, ostream & out);

void printShort(int val, ostream & out);

当我尝试编译我的头文件时，我得到了上面列出的相同错误，但是当我编译我的实现文件时，我得到了一个不同的错误 .

[错误] iostream：没有这样的文件或目录

这是我的实现文件“display.cpp”

我试图寻找错误的解决方案，但几乎所有帖子都是关于linux用户的，以及那些从未回答过问题的帖子 .
