我刚开始使用C ++,正在阅读电子书,从C ++第7版开始。我从书中复制了代码,并将其放入带有预编译头的新项目w32控制台应用程序下的Visual中。好吧,当我在预处理器指令行中使用iostream时,我得到了..我到处搜索,不明白为什么iostream无法正常工作,有帮助吗?

C1010: unexpected end of file while looking for precompiled header.
Did you forget to add '#include "StdAfx.h"' to your source?

    15 cin >> rate;

    17 // Calculate the pay.
    18 pay = hours * rate;
    19
    20 // Display the pay.
    21 cout << "You have earned $" << pay << endl;
    22 return 0;
    23 }

最佳答案

不是因为iostream,而是因为您忘记了包含stdafx.h

这个错误很明显。如果使用预编译头构建项目,则必须在实现文件的开头包含stdafx.h

关于c++ - Visual C++不允许iostream,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/9291485/
