I have met some errors when I try to complie two cpp files at once in vscode [duplicate]

I am a beginner in learning c++.And here are the details: this is the _test.cpp

#include <iostream>
#include "cat.h"
using namespace std;
int main() {
    speak();
}

and cat.h

#pragma once
void speak();

cat.cpp

#include "cat.h"
#include <iostream>
void speak() {
    std::cout << "meow!!" << std::endl;
}

when I use a powershell to compile them, it's ok.

But when i try to CompileRun the _test.cpp, the errors come. enter image description here

when I CompileRun the cat.cpp, it tells me : enter image description here

And here are my tasks.json and launch.json:

I have searched related questions on youtube and google and have viewed some posts on stackoverflow. So I have modified tasks.json and launch.json. But I can't solve the questions I was wondering if there is a way for me to just run the _test.cpp file and it works!
