Need some help on this one

Not getting this one.

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            String readConsole;
            Console.Write("Enter the number of times to print \"Yay!\": ");
            result = Console.ReadLine()
            Convert.ToInt32(readConsole);
            int number;
            Console.WriteLine(number = "Yay!");


        }
    }
}

The code example looks like it will fail. "readConsole" has not been initialized with a value, so the static method "Convert.ToInt32()" will throw an exception. "Console.ReadLine()" expects user input, but "result" has not been declared properly, and it will not compile. "number" has been declared properly, but you cannot assign a string value to an integer.

I hope that helps, Dan

Dan Henning pointed out pretty much all the issues with your code in his comment. In summary:

  • readConsole doesn't have a value, so the call Convert.ToInt32(readConsole) will cause an exception.
  • result is never defined, so compiler error.
  • number is defined as an int and cannot be assigned a string value.

On top of these issues, there are some missing elements, namely a loop. So let's start from the top.

First, it appears that you intended to use readConsole where you actually used result. That is easily fixed by replacing result with readConsole.

Now, as the instructions hint at, you will need a loop in order to accomplish the task of printing out "Yay!" the specified number of times. You could either use a for loop here or a while loop. I would recommend using a for loop, but a while loop will also work; you would just need to remember to increment the counter variable inside the loop.

Here is just a snippet of what the for loop would look like:

for (int i = 0; i < number; i++)
{
    Console.WriteLine("Yay!");
}

You will also want to assign the variable number with the return of the Convert.ToInt32(readConsole) call. In other words:

int number = Convert.ToInt32(readConsole);

Hope this helps!
