STEP 2 - Add input validation to your program by printing “You must enter a whole number.” if the user enters a decimal or something that isn’t a number. Hint: Catch the FormatException.
using System;
namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
{
Console.Write("Enter the number of times to print \"Yay!\": ");
var nums = int.Parse(Console.ReadLine());
int tums = 0;
int total = tums + nums;
try
{
while (total > 0)
{
Console.Write("yay");
total --;
}
}
catch (FormatException)
{
Console.WriteLine("You must enter a whole number.");
}
}
}
}
