C程序不工作:程序<path>与代码不存在

Question

长话短说，我正在用c ++ visual studio代码制作一个计算器，但当我调试它时，它会显示如下：在这里输入图像描述。

我从来没有经历过这样的错误：

这是我的代码，如果有帮助的话:D

#include <stdio.h>

double subtraction();

这里还有我的launch.json文件，因为当我收到错误时，它会提示我打开launch.json文件，如下所示

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "C/C++ Runner: Debug Session",
      "type": "cppdbg",
      "request": "launch",
      "args": [],
      "stopAtEntry": false,
      "externalConsole": false,
      "cwd": "c:/Users/ghazi/Desktop/calculator",
      "program": "c:/Users/ghazi/Desktop/calculator/build/Debug/outDebug",
      "MIMode": "gdb",
      "miDebuggerPath": "gdb",
      "setupCommands": [

          "ignoreFailures": true
        }
      ]
    }
  ]
}

请回答这个问题

正如消息所述，您无法执行cal.exe，因为它不存在。

它不存在，因为当您试图构建它时发生了许多错误。其中一些可以在你的截图中看到。

一些错误来自于函数定义中多余的分号。例如，下面的分号不应该存在：

void multiplication();{
    ...
}
