Create a simple program in C++ that...

1) Returns the maximum value of the given array parameter arr whose length is given by the parameter length

int getMax (int arr[], int length);

2) Return the mean/average of the given array. Note: The return type is double, so be careful not to do integer division.

double getMean (int arr[], int length);
