Question

我试图在Visual Studio代码上配置调试器，但无法使其正常工作。我已经在Visual Studio代码上安装了MING-W64和c / c ++扩展，当我运行代码时，这是我尝试在带有cin >> x >> y >> oper;的行上使用断点进行调试时的输出：

这是我要执行的代码。

#include <iostream>
using namespace std;

class Calculator 
{
    public:
    int Calculate(int, int, char); 

};
int main() 
{
    int x,y,result; 
    char oper; 
    cout << "hello! I'm a calculator!" << endl;
    cout << "Please enter num1 operator num2: " <<endl;
    cin >> x >> y >> oper; 
    Calculator c; 
    result=c.Calculate(x,y,oper); 
    cout << "Result is: " << result << endl; 

    cin.ignore(); 
    cin.get();
    return 0;
}

int Calculator::Calculate(int x, int y, char oper)

{
    switch (oper)
    {
        case '+':
            return x+y;
        case '-':
            return x-y;
        case '*':
            return x*y;
        case '/':
            if(y!=0)
                return x/y;
        default: 
            return 0;
    }
}

下面是我的task.json文件：

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "command": "g++ -g Calculator.cpp -o Calculator", 
            "group": {
                "kind": "build",
                "isDefault": true
            }, "problemMatcher":"$gcc"

        }
    ]
}

这是我的launch.json：

            "args": [],
            "stopAtEntry": false,

            "environment": [],

                    "ignoreFailures": true
                }
            ]
        }
    ]
}

任何帮助将不胜感激。

我遇到了同样的问题，我通过以下方法解决了该问题：

（在Linux上）

安装gdb：

sudo apt install gdb

然后重新加载窗口/关闭并重新打开，然后重试。这应该可以解决。

（在Windows上）

使用以下配置创建c_cpp_properties.json文件：

{
"configurations": [
    {
        "name": "Win32",
        "includePath": [
            "${workspaceFolder}",
            //the path to your c++ folder in the mingw, in my case:
            "C:\\MinGW\\lib\\gcc\\mingw32\\8.2.0\\include\\c++"

        ],
        "defines": [
            "_DEBUG",
            "UNICODE",
            "_UNICODE"
        ],
        "browse": {
            "path": [
                "${workspaceRoot}",
                "C:\\MinGW\\lib\\gcc\\mingw32\\8.2.0\\include\\c++"
            ]
        },
        "intelliSenseMode": "msvc-x64"
    }
],
"version": 4

}

然后，创建具有以下规范的launch.jason文件：

{
"version": "0.2.0",
"configurations": [
    {
        "name": "(gdb) Launch",
        "type": "cppdbg",
        "request": "launch",
        "program": "${workspaceFolder}/file_name.exe",
        "args": [],
        "stopAtEntry": false,
        "cwd": "${workspaceFolder}",
        "environment": [],
        "externalConsole": true,
        "MIMode": "gdb",
        //miDebuggerPath, normally as folow:
        "miDebuggerPath": "C:\\Mingw\\bin\\gdb.exe",
        "setupCommands": [
            {
                "description": "Enable pretty-printing for gdb",
                "text": "-enable-pretty-printing",
                "ignoreFailures": true
            }
        ],
         //optional, if you want to automatically build it
        "preLaunchTask": "build"
    }
]

}

您还将需要一个taks.json文件：

{
"version": "2.0.0",
"tasks": [
    {
        "label": "build",
        "type": "shell",
        "command": "g++ -g file_name.cpp -o output_name.exe",
        "group": {
            "kind": "build",
            "isDefault": true
        }
    }
]

}

*编辑：以前我只是告诉过如何在Linux上修复它，还介绍了如何在Windows上进行配置。
