Answer:
#include <iostream>
#include <random>
//here we are passing our array and a int by ref
//to our function called calculateAverage
//void is infront because we are not returning anything back
void calculateAverage(int (&ar)[100], int &average){
int sum = 0;
for(int i = 0;i < 100; i++){
//adding sum
sum += ar[i];
}
//std:: cout << "\naverage \t\t" << average;
//calculating average here
average += sum/100;
}
int main() {
int value = 0;
int average = 0;//need this to calculate the average
int ar[100];
//assign random numbers from 500 to 1000
//to our array thats called ar
for(int i = 0; i < 100; i++){
value = rand() % 500 + 500;
ar[i] = value;
}
calculateAverage(ar,average);
// std:: cout << "\naverage should be \t" << average;
}
Explanation:
not sure how else this would work without having to pass another variable into the function but I hope this helps!
I commented out the couts because you cant use them according to ur prof but I encourage you to cout to make sure it does indeed calculate the average!
