【问题描述】：

我目前正在参加 C++ 编程基础课程。我已经设置了 Visual Studio 2017 并尝试运行教科书中的示例代码。每当我尝试调试任何东西（包括示例“hello world”代码）时，都会收到这些错误。

我已尝试更改项目的位置并三重检查代码。

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

int main()

    std::cout << "Hello World!\n"; 

它应该输出“hello world”，但我得到了这些错误。

【问题讨论】：

顺便说一句，我强烈建议不要使用预编译的头文件，例如pch.h 直到您有信心编写大型程序。对于小程序来说，好处可以忽略不计。

其中大部分是警告，表明无法找到 DLL 的调试符号。你仍然可以调试你的程序；您希望能够扩展到任何 DLL 函数（通常不需要）。

应该有一个副本...

似乎没有任何错误。我认为您的程序运行，将其文本输出到控制台窗口（您可能错过了，因为它非常快），然后立即退出。在开始调试会话之前尝试设置断点 (F9)。无论如何，您都应该在 int main() 正文中添加 return 0;。

【参考方案1】：

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 Tools->Options->Debugging->Symbols 并选中“Microsoft Symbol Servers”复选框，Visual Studio 将自动下载 PDB 文件。
