Array access problems when converting mql4 to mql5

[Rabia Yoruk]

Hi, i have an two error about the array when i converting mql4 codes to mql5, can anyone help me, when i fix those according to mql document, it seems again (most probably i miss something). I shared the codes below. Thanks in advance.

i declare HT1 array like this : 

double HT1[][4];

First problem is : invalid array access problem for the HT1 array : 

            for(i=0;i<4;i++){

               qTL=NormalizeDouble(qLevel+HT[i],qPoint);

               HT1[i]=NormalizeDouble(qLevel+HT[i],qPoint); //error in this line

             }

Second problem is : parameter conversion not allowed for the HT1 array : 

error in this line, when i called the function like this : 

GetSortedArrayDesc(HT1);

and the function : 

void GetSortedArrayDesc[4](double &d[4])
{
   
   for (int i = 0 ; i < 4; i++)
   {
      for (int j = i ; j < 4; j++)
      {
         if(d[j] < d[i])
         {
            double dumi = d[i];
            d[i] = d[j];
            d[j]= dumi;
         }
      }      
   }    
}

1. Rabia Yoruk: First problem is : invalid array access problem for the HT1 array : 

   double HT1[][4];
   ⋮
                  qTL=NormalizeDouble(qLevel+HT[i],qPoint);
   
                  HT1[i]=NormalizeDouble(qLevel+HT[i],qPoint); //error in this line

   You declared a two-dimensional (2D) array and then are trying to access it as a 1D array.
   

2. Rabia Yoruk: 

   void GetSortedArrayDesc[4](double &d[4])

   A function call is not an array. You pass a 2D array to a parameter declared as 1D.

How about using the MQL5 array functions instead of rolling your own:

// GetSortedArrayDesc(HT1);
ArraySort(HT1); // sort ascending order
ArrayReverse(HT1); // descending order

thank you for your reply, when i fix the those problems like below, it is fixed now.

double HT1[4],LT1[4];

thanks for your reply too, i convert my funcs to what your said however the error is 'ArrayReverse' - function not defined , so mql5 doesnt recognize the ArrayReverse function in my indicator.

It's also available in MQL 5, see https://www.mql5.com/en/docs/array/array_reverse.

Show your code if it doesn't compile.
