VS Code in conjunction with C++ (windows)

Help run (i.e. build (build) and debug) c++ code in VSCode on windows 10. I already have VS Community 2017 installed and the C/C++ extension.
You often have to open single-file programs. That's what I want to use VS Code for. The possibility of debag is not important, but if there is a possibility, then tell me.

#include <iostream>

int main(){
    std::cout<<"Hello World!";
}

What I'm already doing. Using this instruction, I can build a project.
To do this:
1. Install the plugin and restart the program
2. Open VSCode.
3. "File-Open folder" and select the folder where the code is located
4. In the folder with your code, create a file: build.bat, where we insert this code:

@echo off
call "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x64
set compilerflags=/Od /Zi /EHsc
set linkerflags=/OUT:hello.exe
cl.exe %compilerflags% replay.cpp /link %linkerflags%

5. In the folder open the file with the code and press ctrl+shift+B
6. 7. 8. 9. In the public folder, you receive the folder ".vscode" and in it "tasks.json" 10. In place of this insert this:

{
   "version": "0.1.0",
    "windows": {
        "command": "build.bat",
        "isShellCommand": true,
        "showOutput": "always"
    }
}

11. Press ctrl+shift+B again and see that the file has been created hello.exe and others.

Is there any way to automate this process? Even in the bat file, you can somehow pass the name of the cpp file, so that the exe would be with the same name? What's wrong with my encoding maybe who knows? And I can't start debugging.
