Question

Write a program that first reads an integer for the array size, then reads double values into the array, and displays the number of values greater than the average. Enter array size: 6 Enter a number: 1.1 Enter a number: 2.2 Enter a number: 3.4 Enter a number: 3.9 Enter a number: 5.5 Enter a number: 8.75 The number of values greater than the average is 2

Answer 1

Solution :

#include<iostream>
using namespace std;

int main()
{
   int n;
   cout<<"Enter array size: ";
   cin>>n;
   double arr[n], sum = 0;

// read values from user and store it to array and calculate sum of elements
   for(int i=0; i<n; i++){
       cout<<"Enter a number: ";
       cin>>arr[i];
       sum = sum + arr[i];
   }

// calculate average
   double avg = sum / 6;
   int count = 0;

// count number of elements greater than average
   for(int i=0; i<n; i++)
       if(arr[i] > avg)
           count++;
   cout<<"The number of values greater than the average is "<<count<<endl;      
   return 0;
}
