An expression in a condition in your loop

for(int i=0; *(arr i)<=length; i  ) //WE TAKE i<=length BECAUSE THE STRLEN FUNCTION DOESNT COUNT \0

*(arr i) means a value of the array arr at offset i, or simply arr[i] that is easier on the eyes.

Now, why does arr[i] must be less than or equal to length?

Also your comment on that line makes no sense. Although the terminating 0 is not counted, you don't need to convert it to Morse code. In fact, there is no encoding for \0. So the condition should be < length.

Oh, and you don't need to invent a function for getting the length of the string, there are couple of them available.

On the other hand, you don't even need to know the length of your string, just go until you see that \0.

instead of using pointer ptr use the name of the array
