Program that adds input numbers until user inputs "0"

Song Lee

Hello again, C# corner users!
I need to make a program that will add numbers that user inputs, until user inputs 0.

It should look like this at the end:

----------------------------------------------------
[Summation of Real numbers]
Write 0 to Finish

Write an amount to sum or 0 to finish: 50
Write an amount to sum or 0 to finish: 40
Write an amount to sum or 0 to finish: 10.5
Write an amount to sum or 0 to finish: 0

The sum is : 100.5

----------------------------------------------------

Below are the outlines that I got so far:

Thanks for your help guys!

public class FloatNumbersWhileAdd

{

private double sum;

public void Start()

{

WriteProgramInfo();

ReadInputAndSumNumbers();

ShowResults();

}

private void WriteProgramInfo()

{

// Coding part here

}

private void ReadInputAndSumNumbers()

{

bool done = false;

while (!done)

{

// Coding part here

}

private double ReadInput()

{

Console.Write("Write an amount to sum or zero to finish: ");

double num = double.Parse(Console.ReadLine());

return num;

}

private void ShowResults()

{

// Coding part here

}

Yes, there are too many methods though I suspect that this is a template you've been given to work to rather than a conscious decision on your part.

Anyway, I've filled in the gaps and it seems to be working OK:

using System;

public class FloatNumbersWhileAdd
{
private double sum;

public void Start()
{
WriteProgramInfo();
ReadInputAndSumNumbers();
ShowResults();
}

private void WriteProgramInfo()
{
Console.WriteLine("[Summation of Real numbers]");
Console.WriteLine("Write 0 to Finish\n");
}

private void ReadInputAndSumNumbers()
{
bool done = false;
while (!done)
{
double number = ReadInput();
if (number != 0)
{
sum += number;
}
else
{
done = true;
}
}
}

private double ReadInput()
{
Console.Write("Write an amount to sum or 0 to finish: ");
double num = double.Parse(Console.ReadLine());
return num;
}
private void ShowResults()
{
Console.Write("\nThe sum is : " + sum);
}

}

class Program
{
static void Main()
{
FloatNumbersWhileAdd fnwa = new FloatNumbersWhileAdd();
fnwa.Start();
Console.ReadKey();
}
}

Thank you again, Vulpes!
You are such a good helper.

You are breaking because you wrote two many methods. Methods are good but make sure you use it logically. You don't have to break this so much as it is accepted to be in part of only one method for small program like this.
