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.
