Write a C# Sharp program to read 10 numbers and find their average and sum.

Sample Solution:

C# Sharp Code:

using System;  // Importing necessary namespace

public class Exercise4  // Declaration of the Exercise4 class
{  
    public static void Main()  // Main method, entry point of the program
    {       
        int i, n, sum = 0;  // Declaration of variables 'i' for iteration, 'n' to store each number, and 'sum' to store their total sum
        double avg;  // Declaration of variable 'avg' to store the average

        Console.Write("\n\n");  // Displaying new lines
        Console.Write("Read 10 numbers and calculate sum and average:\n");  // Displaying the purpose of the program
        Console.Write("----------------------------------------------");  // Displaying a separator
        Console.Write("\n\n");
	
        Console.Write("Input the 10 numbers : \n");  // Prompting the user to input 10 numbers
        for (i = 1; i <= 10; i++)  // Loop to read 10 numbers
        {
            Console.Write("Number-{0} :", i);  // Prompting for each number with its respective index

            n = Convert.ToInt32(Console.ReadLine());  // Reading each number entered by the user
            sum += n;  // Adding each number to the sum
        }

        avg = sum / 10.0;  // Calculating the average by dividing the sum by 10 (the number of values)

        Console.Write("The sum of 10 numbers is : {0}\nThe Average is : {1}\n", sum, avg);  // Displaying the total sum and average of the 10 numbers
    }
}

Sample Output:

Read 10 numbers and calculate sum and average:                                                                
----------------------------------------------                                                                
                                                                                                              
Input the 10 numbers :                                                                                        
Number-1 :2                                                                                                   
Number-2 :4                                                                                                   
Number-3 :6                                                                                                   
Number-4 :8                                                                                                   
Number-5 :10                                                                                                  
Number-6 :12                                                                                                  
Number-7 :14                                                                                                  
Number-8 :16                                                                                                  
Number-9 :18                                                                                                  
Number-10 :20                                                                                                 
The sum of 10 no is : 110                                                                                     
The Average is : 11
