Question

Part (a) Repeatedly prompt for a number and sum it. When the sum just exceeds 100, stop the prompting and display the sum at the end. You must not display the sum while the user in typing in numbers. (You do not need a counter but you will need some way of terminating the loop)

Part(b)Same as the previous question but additionally displays the average of the numbers when the loop terminates. You will need a counter but not as a loop terminator.

Can you do part a and b on separate codes and both in C#. Thank you :)

Answer 1

a)

C# code:

using System;
class Program{
static void Main(){
        //initializing sum as 0
        int sum=0;
        //looping till sum exceeds 100
        while(sum<=100){
            //asking for number
            Console.Write("Enter number: ");
            //accepting it
            sum+=Convert.ToInt32(Console.ReadLine());
        }
        //printing sum
        Console.WriteLine("Sum: "+sum);
}
}

b)

C# code:

using System;
class Program{
static void Main(){
        //initializing sum as 0
        int sum=0;
        //initializing count as 0
        int count=0;
        //looping till sum exceeds 100
        while(sum<=100){
            //asking for number
            Console.Write("Enter number: ");
            //accepting it
            sum+=Convert.ToInt32(Console.ReadLine());
            //incrementing count
            count+=1;
        }
        //printing sum
        Console.WriteLine("Sum: "+sum);
        //printing average
        Console.WriteLine("Average: "+(float)sum/(float)count);
}
}
