c++ - 每当我调试时出现几个错误

Question

我目前正在参加C++编程基础知识类(class)。我已设置Visual Studio 2017，正在尝试从教科书中运行示例代码。每当我尝试调试任何东西(包括示例“hello world”代码)时，都会出现这些错误。

我尝试过更改项目的位置，并三遍检查了代码。

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

int main()
{
    std::cout << "Hello World!\n"; 
}

应该输出“hello world”，但是我却得到了这些错误。

PDB文件是Visual Studio使用的调试信息文件。这些是系统DLL，您没有调试符号。转到“工具”->“选项”->“调试”->“符号”，然后选中“Microsoft符号服务器”复选框，Visual Studio将自动下载PDB文件。
