如何使用iostream編譯C ++代碼包括

Question

我正在嘗試使用Visual Studio 2015編譯一小段C ++代碼，當我包含iostream庫時，出現一些奇怪的編譯錯誤，有人可以幫助我解決嗎？

這是我的代碼

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

int main()
{
    std::cout << "Somethig" << std::endl;
    return 0;
}

這是我編譯時遇到的錯誤

Answer 1

好像是關於我的Visual Studio安裝的問題，我只是重新安裝了它，問題就消失了。

Answer 2

 #include <cstdlib> 

您應該重新安裝Visual Studio，因為我想到的為什么代碼無法編譯的唯一原因就是忘記了庫標頭
