Question

Write a function named stats, that takes an array and the number of elements in the array as arguments. It must compute and print the minimum value in the array, maximum value in the array and the average value of all the values inside the array.

• Your function MUST be named stats
• Your function has two parameters in the following order:
  • an array of type double
  • The number of elements in the array, type int
• Your function should NOT return anything.
• You function should output the values with 2 decimal places of precision Hint: use fixed and setprecision()

Answer 1

// do comment if any problem arises

//code

#include <iostream>

#include <iomanip>

using namespace std;

void stats(double array[], int n)

{

    // declare required variables

    double min = array[0];

    double max = array[0];

    double sum = 0;

    // loop through array

    for (int i = 0; i < n; i++)

    {

        // if current element is minimum than min

        if (min > array[i])

            min = array[i];

        // if current element is maximum than max

        if (max < array[i])

            max = array[i];

        // compute sum

        sum += array[i];

    }

    cout << "Minimum element: " << fixed << setprecision(2) << min << endl;

    cout << "Maximum element: " << fixed << setprecision(2) << max << endl;

    // compute average and print it using sum

    double average = sum / n;

    cout << "Average: " << fixed << setprecision(2) << average << endl;

}

int main()

{

    // array for testing

    double array[] = {3.3, 6, 23, 90.2, 45};

    stats(array, 5);

}

Output:

Minimum element: 3.30 Maximum element: 90.20 Average: 33.50
