This is the standard guess the animal game.. I am getting an index out of bounds
at line Words[Words.Length] = Input;
.. the new animal and clues entered also needs to be available the next time i play the game..
Instead string []
use List<T>
from System.Collections.Generic
And you can use Add method to add new value like this.
Console.WriteLine("Enter an animal name: \n");
Input = Console.ReadLine();
Words.Add(Input);
And if want an array at the end, you can use ToArray
method. Like this.
Words.ToArray();
Adding a string to a finite array such as the one you have declared causes this additional item to be beyond the bounds of this array, ie. you are squeezing more things into a space that cannot hold that amount. Once created (at compilation) this size is fixed and can't be changed until next time.
I think what you are looking for are lists List<string>
that use list.Add()
to easily manipulate content dynamically during runtime.
Let me know if that answers your question or if you require more details.
You can use List<string>
instead of Array
. Your code throw exception because you are trying to add element to an Array in outranged index. I modified your code like this;
string Input = "";
var Words = new List<string> { "elephant", "lion" };
var Clues = new List<string> { "Has trunk?", "Is gray?", "Is yellow?", "Has mane?" };
Console.WriteLine("Do you want to add you own animal? y/n ? \n");
Input = Console.ReadLine();
if (Input == "Y" || Input == "y")
{
Console.WriteLine("Enter an animal name: \n");
//Array.Resize(ref Words, Words.Length + 1);
Input = Console.ReadLine();
Words.Add(Input);
Console.WriteLine("Enter 2 clues \n");
for (int i = 1; i <= 2; i++)
{
Console.WriteLine("Clue" + i + ":");
var clueInput = Console.ReadLine();
Clues.Add(clueInput);
}
}
why don't you use List rather Array.
string Input = "";
List<string> Words = new List<string>(){ "elephant", "lion" };
List<string> Clues =new List<string>() { "Has trunk?", "Is gray?", "Is yellow?", "Has mane?"};
Console.WriteLine("Do you want to add you own animal? y/n ? \n");
Input = Console.ReadLine();
if (Input.toLower() == "y")
{
Console.WriteLine("Enter an animal name: \n");
//Array.Resize(ref Words, Words.Length + 1);
Input = Console.ReadLine();
Words.Add(Input);
Console.WriteLine("Enter 2 clues \n");
for (int i = 1; i <=2 ; i++)
{
Console.WriteLine("Clue" + i + ":");
Clues.Add(Console.ReadLine());
}
}
please follow this.
`Console.WriteLine("Enter an animal name: \n");
//Hear Words length is 2 and Data (0 = elephant,1 = lion)
Array.Resize(ref Words, Words.Length + 1);
//Hear Words length is 3 and Data (0 = elephant,1 = lion,2 = null)
Input = Console.ReadLine();
//if you write Words[Words.Length] means you tried to access 3 index which is not available.
//You should write this.
Words[Words.Length - 1] = Input;`
