Merge Sort and Quick Sort

Griffinflame21 (47)
I'm trying to implement these 4 different types of sorts and see the times it takes for them to run, but I am having trouble with merge sort and quick sort. I think I did quick sort right but something is wrong because when it compiles there are errors specifically for the quick sort (I pasted the error message at the bottom). And I don't even know where to start with merge sort, I've looked at a lot of examples but I just don't understand it or how to implement it in my program.

I'm also getting these errors when I try to run it

you need to call quicksort with the array to be sorted, 0 (first index in array) and max (last index in array, size-1).
