I am a beginner at using VS code. I tried to run a simple algorithm, but it was difficult.

I get errors:
launch: program ‘/Users/#####/Desktop/C++College/C++HW/main’ does not exist
And
The preLaunchTask ‘C/C++: clang build active file’ terminated with exit code -1.

I have no idea what is wrong, It is a simple program, and I don’t understand what configurations are missing. I use Mac

    "version": "0.2.0",
    "configurations": [
        {
            "name": "(lldb) Attach",
            "type": "cppdbg",
            "request": "attach",
            "program": "enter program name, for example ${workspaceFolder}/a.out",
            "MIMode": "lldb"
        }

    ]
}

and my main

#include <iostream>
#include <string>
using namespace std;

int main() {
 string cars[4] = {"Volvo", "BMW", "Ford", "Mazda"};
 cars[0] = "Opel";
 cout << cars[0];
 return 0;
}
