I didn't really get why "index++" stops the loop ? What does this index++ exactely mean ?

The ++ operator increments the variable. So if index is set to zero, index++ will increment it by one to 1.
For a while loop, does the loop have a condition attached to it? Like while index is less than 10, keep repeating the code. In that instance, index++ will halt the execution of the loop as soon as it has run enough times to make index equal to 10.
I hope that makes sense.
Steve.
