7,427 PointsWhy won't it print my else if?
I don't understand why it won't print my else if when the user inputs a negative number. It prints nothing. What am I doing wrong here?
using System;
namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
{
Console.Write("Enter the number of times to print \"Yay!\": ");
var a = Console.ReadLine();
try
{
var b = int.Parse(a);
for(int n=0; n<b; b--)
{
if (b > 0)
{
Console.Write("Yay!");
}
else if (b < 0)
{
Console.Write("You must enter a positive number.");
}
else
{
Console.Write("Not a valid input."); continue;
}
}
}
catch(FormatException)
{
Console.Write("You must enter a whole number.");
}
}
}
}

It doesn't need to be done more than once, and the loop will not run at all if the value of "b" is less than 0.
You also don't need any conditional around the output statement inside the loop. The loop itself controls the number of outputs.
