Yeah, as the title says.. what am I doing wrong? I am getting tired of it. I haven't even been taught how to loop words like this..
using System;
namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
{
Console.Write("Enter the number of times to print \"Yay!\": ");
var entry = int.Parse(Console.ReadLine());
try
{
for(var i =0; i < entry; i++);
{
Console.Write("Yay!");
Console.WriteLine("Yay was printed " + entry + " times!");
}
}
catch(FormatException)
{
Console.WriteLine("Error!");
}
}
}
}

- there's a stray semicolon at the end of the "for" line that is preventing the following block from being looped
- for the "try" to detect conversion issues, the int.Parse must be done inside the "try" block
- the message about how many times is not part of the instructions and confuses the verifier
- the challenge expects the error message to be "You must enter a whole number." instead of "Error!"

while(count > 0) {
Console.WriteLine("Yay!");
count--;
}
For the try catch you wanna use something like this, Remember to declare count outside of the try-catch!
int count;
try{
count = int.Parse(Console.ReadLine());
} catch(FormatException) {
Console.WriteLine("You must enter a whole number.");
}
Anyone more questions let me know! Hope this helps, and Happy coding :)

1,396 PointsAh Okay, i will have a look at it tomorrow then. Haha Yeah I just wrote ettor because Iām just at the First step and added try and Catch because I checked the community answers to compare and they had try and Catch in theirs so I just added it!
You are extremely quick to answer questions! Keep it up!

231,269 PointsI just happened to be online! And I just figured you were on step 2, you'll need to do those things then.
But to get the most out of the challenges, you should really try to write them yourself. You might look around for examples but don't just paste them in, you're likely to be getting someone else's mistakes like this time!
And just in general, do only what the challenge asks for in each task. Even good code that does extra stuff can throw off the verifier.
