Se citesc de la tastatura n numere intregi . sa se calculeze media aritmetica a numerelor pare.(c++)

Answer 1

o varianta

#include<iostream>
using namespace std;
int main () {
int i,n,a[50];
int media=0;
int contor=0;
cout<<"Introduceti parametru n ";cin>>n;
cout<<"Introduceti numerele\n"; for(i=1;i<=n;i++) {
cout<<"numar["<<i<<"]="; cin>>a[i];
}
for(i=1;i<=n;i++) {
if (a[i]%2==0) {
media+=a[i];
contor++;
}
}
cout << "au fost gasite "<<contor<< " numere pare."<<endl;
if (contor>1){
cout<<"media este="<<media/contor<<endl;
}else{
cout<<"media nu poate fi efectuata"<<endl<<"numere pare gazite="<<contor<<endl;
}
}
