使用 gcc 在 vscode 中构建和运行 C++ 代码时出错。任务.json 文件

Question

这是我试图构建和执行的代码。

#include <iostream>
#include <stdio.h>

using namespace std;

int main()
{
     cout << "Hello World";
     return 0;
}

我可以使用命令编译和运行它

directory path:// g++ -g hello.cpp

./a.exe

我现在制作了一个tasks.json 文件，这样我就不必每次都运行上述两个命令，并且.exe 文件也与.cpp 文件命名相同。

这是我面临的错误： image for build error in VSCode terminal

如果有人知道解决此问题的方法，请帮助我。 如果您需要tasks.json 文件内容，请告诉我。我会把它们放在这里。

Tasks.json

    "tasks": [

            "args": [
                ";",
                "g++",
                "-g",
                "${file}",
                "-o",
                "ans.exe",
