Debugging C++ in Visual Studio Code

I just want to learn how to debug in Visual Studio Code as i do not want to download a heavier IDE as VS2019 for example. Here is the simple program i want to debug without any breakpoints whatsoever.

#include <iostream>   
void print(std::string arg){
  std::cout << arg << std::endl;
}

int main(){
  std::string name = "Name";
  print(name);
  return 0;
}

It "debugs" but i don't see anything as i expected to see. No memory no outputs just this in terminal:

Name [1] + Done "/usr/bin/gdb" --interpreter=mi --tty=${DbgTerm} 0<"/tmp/Microsoft-MIEngine-In-ycr78o29.7j7" 1>"/tmp/Microsoft-MIEngine-Out-epnjc9my.6yh"

And this in debug console:

I understand that the first part is literally a license but i just don't get if this is supposed to be like this? I thought we were supposed to see line by line what is happening and this finished in seconds.

Thanks.
