# count the number of elements in an array

• ### Question

• Hi all, I apologize for my English, I'm using google translator.
I would like to create a function that matters to me the number of identical elements within an array.
In a nutshell if I have an array that contains the elements:  HELLO | GOAL | HELLO | TOAST | HELLO
The result of the function must be: HELLO -> 3 GOAL -> 1, TOAST -> 1

Thank you all for the help

arr="1=HELLO;2=GOAL;3=HELLO;4=TOAST;5=HELLO"
For i=1 To Array.GetItemCount(arr)
count[arr[i]]=count[arr[i]]+1
endfor
cnt=Array.GetAllIndices(count)
For i=1 To Array.GetItemCount(count)
TextWindow.WriteLine(cnt[i]+"  "+count[cnt[i]])
EndFor
