C# Final part 3 of 3. How does my code look? All I added since part 2 was an "if/else" statement. Thanks much!

Since i have only added an "if/else" statement to the code I think it should work but a second set of eyes would be of benefit. Those more experienced than mine in particular!

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            Console.Write("Enter the number of times to print \"Yay!\": ");
            var numOfTimes = Console.ReadLine();
            try
            {
                int num = int.Parse(numOfTimes);
                if (numOfTimes < 0)
                {
                    Console.WriteLine("You must enter a positive number.");
                }
                else 
                {
                    for (int i = 0; int < num; int ++)
                    {
                        Console.WriteLine("\"Yay!\"");
                    }
                }
            }
            catch (System.FormatException)
            {
                Console.WriteLine("You must enter a whole number.");
            }
        }
    }
}

Hi there! I think you're doing fairly well, but the biggest problem here is your for loop. I believe it must have been edited somehow as I don't believe it would have or should have passed the first step. The int you are using is a keyword reserved by C# for the integer data type. But you should be comparing an integer here (namely num). I edited your code so that it passes, and will go through it with you a bit.

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            Console.Write("Enter the number of times to print \"Yay!\": ");
            var numOfTimes = Console.ReadLine();  // here you read in a number from the user as a string
            try
            {
                int num = int.Parse(numOfTimes);  // we're trying to parse a number out of the string they entered
                if (num < 0)  // If the number was negative
                {
                    Console.WriteLine("You must enter a positive number.");  // tell them they need a positive number
                }
                else   // otherwise
                {
                    for (int i = 0; i < num; i++)  // start a counter at 0.  While the counter is less than the number we parsed out, increment the counter
                    {
                        Console.WriteLine("\"Yay!\"");  //Write out Yay!
                    }
                }
            }
            catch (System.FormatException)
            {
                Console.WriteLine("You must enter a whole number.");  //If the number could not be parsed, tell the user they must enter a whole number
            }
        }
    }
}

Hope this helps! :sparkles:

This was very helpful, thanks much! The explanations that were next to each line of code helped me understand the process better.
