Python Web Development Techdegree Student 1,110 PointsI Don't know how to fix the error
the preview shows
System.ArgumentOutOfRangeException: startIndex cannot be larger than length of string. Parameter name: startIndex at System.String.Substring (Int32 startIndex, Int32 length) [0x0009c] in /builddir/build/BUILD/mono-4.4.2/external/referencesource/mscorlib/system/string.cs:1266 at System.String.Substring (Int32 startIndex) [0x00000] in /builddir/build/BUILD/mono-4.4.2/external/referencesource/mscorlib/system/string.cs:1232 at MonoTester.Run () [0x001b6] in MonoTester.cs:132 at MonoTester.Main (System.String[] args) [0x00013] in MonoTester.cs:28
what dose that mean
using System;
namespace Treehouse.CodeChallenges
{
class Program
{
static void Main()
{
int a =0;
try
{
a = Convert.ToInt32(Console.ReadLine());
for (int i=1; i<=a+1; i++)
{
Console.Write("Enter the number of times to print \"Yay!\": " + i);
}
}
catch( FormatException)
{
Console.Write("You must enter a whole number");
}
}
}
}

231,236 PointsYou should go back to task 1.
I tried this in the challenge, and it passed task 1 — but it should not have, and the problems will become more serious in the latter tasks. Particular issues that need addressing for task 1:
- You don't actually print "Yay!"
- You don't print the prompt until after you take the input.
- You print the prompt in a loop (instead of "Yay!").
- The loop index should not be printed.
Start over at task 1 and be sure to fix these issues, then task 2 should go more smoothly.
