Question

This final code challenge will require you to use almost everything we've covered in this course. You’ll write a program to celebrate completing this course by printing “Yay!” to the screen a given number of times. Write a program that: Prompts the user to enter the number of times to enter “Yay!”. I've done this for you. Leave this as it is. Prints “Yay!” to the screen that number of times (Hint: You’ll need a loop for this. You’ll also need to keep track of how many times the loop has run). You can print them all on the same line or on separate lines.

Program.cs

using System;

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

        } if (counter < times) 
        {
          Console.Write("Yay!");
          int  counter = 1;
        }
    }
}

The first part can work like this

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
           Console.Write("Enter the number of times to print \"Yay!\": ");
            var response = Console.ReadLine();
            int count = Int32.Parse(response);
            for(int i = 0; i < count; i++)
            {
             Console.WriteLine("Yay");   
            }
        }
    }
}

I did 4 things here:

Read the response in a var type variable, since ReadLine reads things as strings.
Used another variable of type int to save the result of the Int32.Parse() function. I did this because converting the response from string to int is needed to run counting loops.
Processed the response into a for loop. Inside of the first condition, I declared a basic int variable "i" and set it equal to 0 so that the count goes up by one until the count variable is reached. Just remember that 0 is the first time it runs. So if the user says 5. It will run at i = 0, 1, 2, 3, 4 (5 numbers total).
Used Console.WriteLine to process the response that the prompt asked for. Technically, the assignment will let you also use Console.Write, but Console.WriteLine is a little bit neater in this case, so I used that.

It is also worth mentioning that you could have encapsulated the Console.WriteLine("Yay"); code using a while loop. If you want, I can show you how that works too.

Let me know if you want help with the next step (Hint: using an "if" conditional is needed, and possible a do-while loop).

You forgot to read the input with ReadLine and you need to convert the input type because you want an int type and the defaul type from Readline is string.

Convert code:

Convert.ToInt32(Console.ReadLine());

For the loop you can use a while or a for loop but you wanna decrease the counter number by 1 each time the loop runs. An if statment checks only ones if the statment is true and then jumps out in the next line of code.

Hope this helped you :)

Here's a few hints:

Console.Write doesn't return anything
you will need another function to get the user input (such as Console.ReadLine)
you will need to convert the input from a string into a number
you will need to initialize your counter before you begin printing
you will need some kind of loop (such as "while" or "for", instead of "if") to print multiple times
inside the loop you will need to increment the counter

I'll bet you can get it now without a spoiler.
