I'm currently taking the introduction to C++ class. I'm currently ahead of my class so the teacher refuses to answer my questions -_-. I've been reading through my book and looking through the web but I can't understand what my mistake is, can anyone give me hints as to what my mistake is?

Also, I know the code is sort of a mess, I've been messing around with it alot to try and figure out the mistake so there are a few variables and instructions that aren't useful, it's just that I couldn't get my function that calculates the average to work so I just programmed the instructions into the main.

I marked the line with the error with ==><== error here.

Code:#include <iostream> using namespace std; int carre(int x); double average(int a[]); int main() { int n, i, m, entier[5]; double moyenne, moyenne_carre, sum = 0, sum_carre = 0; char check; do { cout << "\nVeuillez entrer 5 valeures entieres : " <<endl; for ( m = 0 ; m <= 4 ; m++ ) cin >> entier[m]; /*for ( m = 0 ; m <= 4 ; m++) sum += entier[m]; moyenne = sum / 5;*/ cout << "La moyenne des chiffres est :"; for ( n = 0 ; n <= 4 ; n++ ) ===> cout << average(entier[n]) << " "; <=== error here /*cout << "Les valeures au carre sont: "; for ( i = 0 ; i <= 4 ; i++ ) cout << carre(entier[i]) << " "; for ( m = 0 ; m <= 4 ; m++ ) sum_carre += carre(entier[m]); moyenne_carre = sum_carre / 5; cout << "La moyenne des chiffres au carre est:" << moyenne_carre << endl; */ cout << "\nEncore? (y/n) :"; cin >> check; } while (check == 'y'); cin.sync(); cin.get(); } int carre(int x) { return x * x; } double average(int a[]) { int avg = 0, sum = 0, n, i = 0; for (n = 0 ; n <= 4 ; n++) { sum += a[n]; i=i++; } avg = sum/i; return avg; }
