915 PointsCannot make it work the way it was asked
using System;
namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
{
int counter = 0;
Console.Write("Enter the number of times to print \"Yay!\": ");
string yaynumber = Console.ReadLine();
string yay = "Yay!";
counter = int.Parse(yaynumber);
for (int i = 0; i <= counter; i++)
{
Console.WriteLine(yay[i].ToString());
}
Console.ReadLine();
}
}
}
This is not printing word yay . Can any help me what i have doing wrong?

It would also cause errors when printing more than 4 lines, since you run out characters in your word. Plus, you also have a stray extra ReadLine after the loop.
See the comments in the corrected code below:
namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
{
int counter = 0;
Console.Write("Enter the number of times to print \"Yay!\": ");
string yaynumber = Console.ReadLine();
string yay = "Yay!";
counter = int.Parse(yaynumber);
for (int i = 0; i <= counter; i++)
{
// Console.WriteLine(yay[i].ToString()); <-- this prints just one letter of the word
Console.WriteLine(yay);; // this prints the whole word
}
// Console.ReadLine(); <-- this waits for input that is not used
}
}
}

915 PointsI tried to toString() already but it did not work.
this code worked but as i typed 0 its still printing one.
using System;
namespace Treehouse.CodeChallenges { class Program { static void Main() { int counter = 1; Console.Write("Enter the number of times to print \"Yay!\": "); string yaynumber = Console.ReadLine(); var yay = "Yay!";
var counter1 = int.Parse(yaynumber);
for (int i = 0; i <= counter; i++)
{
Console.WriteLine(yay);
if (counter1 <= counter)
{
break;
}
else if (counter1 <= 1)
{
Console.WriteLine("please enter valid number");
}
counter += 1;
continue;
}
}
}
}

915 PointsAfter trying again and again. I got this right.
using System;
namespace Treehouse.CodeChallenges { class Program { static void Main() { int counter = 0; Console.Write("Enter the number of times to print \"Yay!\": "); string yaynumber = Console.ReadLine(); var yay = "Yay!";
try{
var counter1 = int.Parse(yaynumber);
while (counter1 <= 0)
{
Console.WriteLine("You must enter a positive number.");
break;
}
for (int i = 0; i <= counter; i++)
{
if (counter1 <= counter)
{
continue;
}
Console.WriteLine(yay.ToString());
counter += 1;
continue;
}
}
catch(FormatException){
Console.WriteLine("You must enter a whole number.");
}
Console.ReadLine();
}
}
}

915 PointsThanks Steven,
using System;
namespace Treehouse.CodeChallenges { class Program { static void Main() { int counter = 1; Console.Write("Enter the number of times to print \"Yay!\": "); string yaynumber = Console.ReadLine(); var yay = "Yay!";
}
This code work perfect if i want to print yay. But it will still print if i enter 0 or -numbers. And it will not continue.

And I was a bit confused by your last comment. Did you mean for that to be a new question?
