3,059 PointsThe use of input validation on the try and catch exception
Add input validation to the below program by printing "You must enter a whole number." if the user enters a decimal or something that isn’t a number.
using System;
namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
{
Console.Write("Enter the number of times to print \"Yay!\": ");
string input = Console.ReadLine();
try
{
int count = int.Parse(input);
}
int i = 0;
while(i < count)
{
i += 1;
Console.WriteLine("Yay!");
}
catch (FormatException)
{
Console.WriteLine("You must enter a whole number.");
continue;
}
}
}
}
