无法在vscode中调试单个.c文件

我认为应该是6个小时我才能解决这个问题！无论如何，我想在linux ubuntu 64bit的vscode中构建一个.c文件 . 这是我的代码（quadratic-equation.c）：

#include <stdio.h>
#include <math.h>

double quadratic_equation(float a, float b, float c);

int main()
{
    float x, a, b, c;

    printf("Enter a: ");
    scanf("%f", &a);

    printf("Enter b: ");
    scanf("%f", &b);

    printf("Enter c: ");
    scanf("%f", &c);

    x = quadratic_equation(a, b, c);
    printf("form: ax%c + bx + c = 0:\n", 253);
    printf("x = %f", x);

    return 0;
}

double quadratic_equation(float a, float b, float c)
{
    float x;

    if(a == 0)
    {
        if(b == 0)
        {
            printf("a & b can not be both zero");
        }
        else
        {
            x = -c / b;
            return x;
        }
    }
    if((b * b - 4 * a * c ) == 0)
    {
        x = -b / (2 * a);
        return x;
    }

    x = (-b + sqrt(b * b - 4 * a * c)) / 2 * a;
    return x;
}

我已经解决了此代码中的所有问题 . 在构建的过程中，VSCode强迫我创建3个文件，c_cpp_properties.json，launch.json和tasks.json . 所以，我复制粘贴它们：我的c_cpp_properties.json文件：

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "/usr/include",
                "/usr/local/include",
                "${workspaceFolder}/**"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE"
            ],
            "compilerPath": "/usr/bin/gcc",
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "clang-x64",
            "browse": {
                "path": [
                    "${workspaceFolder}"
                ],
                "limitSymbolsToIncludedHeaders": true,
                "databaseFilename": ""
            }
        }
    ],
    "version": 4
}

我的launch.json文件：

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/quadratic-equation.c",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "miDebuggerPath": "/usr/bin/gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "build quadratic equation"
        }
    ]
}

我的tasks.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 quadratic equation",
            "type": "shell",
            "command": "g++",
            "args": [
                "-g", "quadratic-equation.c"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ]
}

这是gdb --version输出的内容：

我也尝试添加没有帮助的makefile文件 . （我实际上不知道如何配置它，但我搜索了一下并进行了一些尝试，这没有帮助） . 最后，这是我按f5（开始调试）时得到的错误：

Unable to start debugging. Program path '/home/amirali/XPSC/test/c-cpp/quadratic-equation.c' is missing or invalid.

GDB failed with message: "/home/amirali/XPSC/test/c-cpp/quadratic-equation.c": not in executable format: File format not recognized

This may occur if the process's executable was changed after the process was started, such as when installing an update. Try re-launching the application or restarting the machine.

非常感谢你的帮助
