C# Program for Basic Statistical Operations: Sum, Average, Minimum, and Maximum

This C# program allows the user to input numbers continuously and calculates various basic statistical operations for the entered numbers: the sum, average, minimum, and maximum values. The user is prompted to enter numbers one at a time. After each number is entered, the program updates and displays the total sum, count of the entered numbers, average, minimum, and maximum.

The program will continue prompting the user for numbers until the user enters 0. Upon entering 0, the program will display a farewell message and terminate. The program is designed to handle any sequence of positive or negative numbers, and it will ensure that the statistical operations reflect all of the previously entered numbers.

Objective

Write a C# program to calculate various basic statistical operations: it will accept numbers from the user and display their sum, average, minimum, and maximum, as in the following example:

Number? 5
Total=5 Count=1 Average=5 Max=5 Min=5

Number? 2
Total=7 Count=2 Average=3.5 Max=5 Min=2

Number? 0
Goodbye!

(As seen in this example, the program will end when the user enters 0)

Example C# Exercise

 Copy C# Code 
using System;

class Program
{
    static void Main()
    {
        // Declare variables to keep track of the total sum, count, minimum, and maximum
        double total = 0;
        int count = 0;
        double min = double.MaxValue; // Initialize min to the maximum possible value
        double max = double.MinValue; // Initialize max to the minimum possible value

        while (true) // Infinite loop, continues until the user enters 0
        {
            // Prompt the user for a number
            Console.Write("Number? ");
            double number = double.Parse(Console.ReadLine()); // Read the number entered by the user

            if (number == 0) // If the user enters 0, break the loop and end the program
            {
                Console.WriteLine("Goodbye!");
                break;
            }

            // Update total, count, min, and max
            total += number;
            count++;

            if (number < min) min = number; // Update min if the current number is smaller
            if (number > max) max = number; // Update max if the current number is larger

            // Calculate average
            double average = total / count;

            // Display the statistics
            Console.WriteLine($"Total={total} Count={count} Average={average} Max={max} Min={min}");
        }
    }
}

 Output

//Example 1:
Number? 5
Total=5 Count=1 Average=5 Max=5 Min=5

Number? 2
Total=7 Count=2 Average=3.5 Max=5 Min=2

Number? 0
Goodbye!

//Example 2:
Number? 10
Total=10 Count=1 Average=10 Max=10 Min=10

Number? 4
Total=14 Count=2 Average=7 Max=10 Min=4

Number? -3
Total=11 Count=3 Average=3.66666666666667 Max=10 Min=-3

Number? 0
Goodbye!
