Question

3 essay 10 points write a program that uses a loop to read 5 numbers from the user and prints their average.

Explanation:

Step1: Initialize variables

We need to initialize a variable to store the sum of the numbers (let's call it total) and a variable to keep track of the count of numbers (let's call it count). We'll start with total = 0 and count = 0.

Step2: Use a loop to read numbers

We can use a for loop that runs 5 times. In each iteration, we'll prompt the user to enter a number, convert it to a numeric type (e.g., float or int), add it to the total, and increment the count by 1. For example, in Python:

total = 0
count = 0
for _ in range(5):
    num = float(input("Enter a number: "))
    total += num
    count += 1

Step3: Calculate the average

The average is calculated by dividing the total by the count. So, average = total / count.

Step4: Print the average

We'll print the calculated average. In Python, we can do print("The average is", average).

Putting it all together in Python:

total = 0
count = 0
for _ in range(5):
    num = float(input("Enter a number: "))
    total += num
    count += 1
average = total / count
print("The average is", average)

If we were to use a different programming language like Java, the code would be:

import java.util.Scanner;

public class AverageCalculator {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        double total = 0;
        int count = 0;
        for (int i = 0; i < 5; i++) {
            System.out.print("Enter a number: ");
            double num = scanner.nextDouble();
            total += num;
            count++;
        }
        double average = total / count;
        System.out.println("The average is " + average);
        scanner.close();
    }
}

Answer:

Here is a Python program to solve the problem:

total = 0
count = 0
for _ in range(5):
    num = float(input("Enter a number: "))
    total += num
    count += 1
average = total / count
print("The average is", average)

(Or the equivalent program in your preferred programming language following the same logic of reading 5 numbers, summing them, and dividing by 5 to get the average.)
