Stranger loop !!
By _HossamYehia_, history, 4 years ago, In English

This loop must ends at i = 3

I know the reason of Runtime error, because the last iteration access an index out of array.

But how i becomes greater than 2 ?!!

if(arr[i] > arr[i + 1]);

For i=2 you're accessing arr[3] here, which is Undefined Behavior.
