C++ Coding: Arrays

Given the following code and program output:

#include <iostream>
using namespace std;

double average(const int g[], const int& CAP);
void output(const int *g, const int& GRADES, const double& GPA);

int main() {

const int NUM_GRADES = 5;
int grades[NUM_GRADES] = {10, 15, 20, 25, 30};

//average function is called by output function
output(grades, NUM_GRADES, average(grades, NUM_GRADES));

return 0;
}

Example Output:

10, 15, 20, 25, 30
GPA: 20

Code function definitions for average() and output():

average() accepts the array and its size as input, and returns the average grade with two decimal places.
output() accepts the original array, the array's size, and GPA (generated from the average function) as function parameters. Display the array and GPA.
