Need help with loops

Hi Alex,

The logic you have used so far is totally wrong.
As per your question, you want to add up the numbers entered by the user,
not the numbers from 1 to 999, whereas your code is printing numbers from 1 to 999.

So here's how you can modify the logic.

1. Begin a loop.
2. Accept number from user.
3. Is it 999? Yes, then exit out of the loop.
4. If no, then accumulate the sum.
5. Repeat till user enters 999.
6. Outside the loop, display the accumulated sum.

The code for the above is:

using System;

class Program
{
static void Main(string[] args)
{
int number = 1;
int sum=0;
do{
number = int.Parse(Console.ReadLine());
if(number!=999)
{
sum+=number;
}
else
break;
}
while( number != 999);

// Now sum has accumulated the sum of all numbers excluding 999
Console.WriteLine("The sum is {0}", sum);
}
}
