help with calling functions using arrays

byronflds (119)
The assignment is rather easy we are given a program shell and just have to correctly call the functions. I got the program to compile but the output is not correct and I believe it is due to some of the function prototypes not making sense to me.

these are the prototypes the professor provided:

and this is how I called them:
the functions from step 3 down are whats giving me trouble

the problem i am having is with the
void DisplayArray(int A[], int N, string OutputLabel);

function. It is asking for an int N but not one is given.
