Formal parameters - array problem

[Florin Ionescu]

I read here: https://www.mql5.com/en/docs/basis/variables/formal

and here: https://www.mql5.com/en/docs/basis/function/functionoverload

and this code is supposed to be valid:

double AverageFromArray(const int array[],int startPos = 0, int endPos = -1) {
   int size = ArraySize(array);
   if(size<=0) return 0.0;
   
   if (endPos < 0) endPos=size-1;
   else if (startPos > endPos) return 0.0;
   
   double sum=0.0;
//---
   for(int i=startPos;i<=endPos;i++) sum+=array[i]; 
   double aver=sum/(endPos-startPos+1);
//---
   //Print("Calculation of the average for an array of double type");
   return aver;
  }

 But compiler throws:  'array' - arrays are passed by reference only.

If I remember well, at some point there was a decision to pass arrays only as reference to be able to send fixed length arrays as formal parameters.

I don't know if I'm right. But if this is the case, then documentation has to be changed, right?

It's not thaaat important anyway, but it gets confusing when you copy paste the example and then you get errors.

(this version with const int array[] was attractive, because of naming problems (formal array name coinciding with a global variable name, and then errors))

You are right. Help was fixed, thank you.
