C++ in VS Code, problem declaring an array inside a function using a non const parameter of the function, while it should be possible

Question

I searched for my problem but I couldn't find one.

I'm working with VS Code (version 1.55) in C++. I'm trying to declare 2 arrays inside a function using one of its parameters to define the width. I need this because I have to initialize them, inside the same function, in a different way given their width, like this:

double MyFunc(/*other parameters*/ int points){
  
  double arr1[points];
  double arr2[points];

  if(points == 2){
    // initialization
  }
  else if(points == 3){
    // initialization
  }
  else if(points == 4){
    // initialization
  }
// Operations with the arrays etc
return 1.7;  // Arbitrary value just to make this code working
}

If I save the file like this, VS Code tells me that there's a problem, which is: "expression must have a constant value -- the value of parameter "points" cannot be used as a constant". But I can compile and execute it anyway (I tried with cygwin and it's all ok). Is there a way to get rid of this "false" problem?
