Why wont this code work?

Need help with finding out why this won't compile.

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            Console.Write("Enter the number of times to print \"Yay!\": ");
            int tums = 0;
            string nums = Console.Read();
             int times = Int32.Parse(nums);

            int total = int tums + int times;

            while (total >= 1 )
            {
                Console.Write("yay");
                total = total - 1; 

            } 





        }
    }
}

You can change your code like it

Console.Write("Enter the number of times to print \"Yay!\": "); string nums = Console.Read(); int times = (int)nums;

        while (times>0 )
        {
            Console.Write("yay");
            times--; 
        }

That is absolutely a cleaner way to write it. When I run the code, regardless of the number I type in, it still only prints "yay" once.

you don't need to convert to int again and this statement is not correct like it :

int total = int tums + int times; // Incorect statement

Correct is:

int total = tums + times;

Or

int total = (int)tums + (int)times;

Perfect, I corrected that as well, thank you. The same problem is still persisting. Any suggestion on how to make it repeat the word "yay" for the amount that the user types in?

This compiles for me.

I just changed Console.Read() to Console.ReadLine() and Console.Write() to Console.WriteLine(). Console.WriteLine() will write every "yay" on a new line while Console.Write() prints like yayyayyay...

using System;

namespace Treehouse.CodeChallenges
{
  class Program
  {
    static void Main()
    {
      Console.Write("Enter the number of times to print \"Yay!\": ");
      int tums = 0;
      string nums = Console.ReadLine();
      int times = Int32.Parse(nums);

      int total = tums + times;

      while (total >= 1 )
      {
      Console.WriteLine("yay");
      total = total - 1; // you could write total--; or total -= 1;
      } 
    }
  }
}
