5,766 PointsReally frustrated with this challenge..
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 response = Console.ReadLine();
int count = Int32.Parse(response);
for(int i = 0; i < count; i++)
{
Console.WriteLine("Yay");
} if ()
{
Console.WriteLine("You must enter a whole number.");
}
}
}
}
