我无法使用可视化工作室代码构建C++

我想用C++编译我的"你好世界"，但我做不到。我使用Visual Studio代码，这是我的代码。

当我尝试构建cpp时，错误是：

clang：错误：没有这样的文件或目录："/Users/a1/C++/first">

我的文件是"/Users/a1/C++/first.cpp">

这适用于macOS、High Sierra 10.14和Visual studio代码。

我安装了C/C++，但现在我无法构建我的C++。

#include "stadfx.h"
#include < iostream >
int _tmain(int argc, _TCHAR* argv[]) {
std::cout <<"Hello, World" <<std::endl;
return 0;
}

执行任务：g++/Users/a1/C++/first.cpp-o-g/Users/a1/C++/fist<

clang:error：没有这样的文件或目录：'/Users/a1/C++/first'터미널 프로세스가 종료 코드1(으)로 종료되었습니다.
