We won't do your homework for you but if you show us what you have done so far and where you are stuck perhaps we can help.

Function 3 didnt get. help me how to solve

Please post the code in the thread (not as an attachment that I have to open in another application).

``````#include<iostream>
using namespace std;
void printAverage(int);

int main(){
int n, i;
float num[10], sum=0, average;

for (i = 0; i < 10; ++i) {
cout << i + 1 << " Enter number: ";
cin >> num[i];
sum += num[i];
}
}

void printAverage(int); {
average = sum / 10;
cout << "Sum = " << sum << " Average = " << average << endl;
}``````

Once you have the average, you need another loop that reviews the input against it and prints the desired items.
