Different Array Number

I would have do it so, it's not as nerdy as the above snippet, but it works well : 

#include <Arrays\ArrayInt.mqh> // Include lib
//
int MyArray[]={5,7,5,3,3,4,7,7,3,4,4,3};
//
int CountItem(int &Array[])
  {
   CArrayInt *TempArray=new CArrayInt(); CArrayInt *ItemsFound=new CArrayInt(); int value = 0;
   TempArray.AssignArray(MyArray); TempArray.Sort();
   for(int x=0;x<TempArray.Total();x++) { if(ItemsFound.Search(TempArray.At(x))<0) { ItemsFound.Add(TempArray.At(x)); ItemsFound.Sort(); } else { continue; } }
   printf("*** Items found in array : %g",ItemsFound.Total()); value = ItemsFound.Total();
   delete(TempArray); delete(ItemsFound);
   return(value);
  }
//
DifArrayNbr = CountItem(MyArray); // Function call
//+------------------------------------------------------------------+

I'm assuming from you example you want to suppress sequential duplicates. To do that, just use a hold value.

        int value = 0;
        int holdvalue = -1;
        while ( true )
        {
                // The function gives the values in succession, e.g.
                // 1,1,2,2,1,1,4,4,3, . . . 
                value = one_function();
                
                // Always have a way to get out of an infinite loop
                if ( value == -1 )
                {
                        break;
                }

                // suppress inline duplicates
                if ( value != holdvalue )
                {
                        Print(StringFormat("one_function returned [%d]", value));
                        holdvalue = value;
                }
        }
