Bubble sort algorithm

Question

I need help adjusting my bubble sort algorithm: It's not sorting the array, and at the end returns a random string of numbers. what am I doing wrong?

Answer 1

Use i<size instead of i<=size :)
Since the array size is 4, the valid indices are 0, 1, 2, 3. We can't include 4 as the index.
