In this program, we will learn about taking integer input from the user and storing it in the array. Then we will find the sum of all array elements using for loop and finally calculate the average of N input numbers stored in an array.

Program code:

#include <iostream>
using namespace std;

void func_avg(int *arr, int size){
    float sum = 0,average;
    // Find sum of all array elements
    for(int i = 0; i < size; i++) {
        sum += arr[i];
    }
 
    average = (float)sum / size;
    cout << "Average = " << average;

}
int main() {
    int i, count, sum, inputArray[500];
    float average;
 
    cout << "Enter number of elements\n";
    cin >> count;
     
    cout << "Enter " << count << " elements\n";
    // Read "count" elements from user
    for(i = 0; i < count; i++) {
        cin >> inputArray[i];
    }
    func_avg(inputArray,count);
     
   
    return 0;
}

Output:

Enter number of elements
4
Enter 4 elements
1 2 3 4
Average = 2.5
