	The **`.Substring()`** method is a string method that returns a substring of a string starting at the given index number, it will return all characters unless a maximum length is given. This method returns `Empty` if the index is greater than the length of the string instance.
	The **`.Substring()`** method is a string method that returns a substring of a string starting at the specified index. It will return all characters from that index to the end unless a maximum length is specified. If the starting index equals the string length, it returns an empty string (`""`). If the index is greater than the string length, it throws an `ArgumentOutOfRangeException`.

[mamtawardhani]

corrected the definition as it does not return Empty

[mamtawardhani]

We can write this as:

.Substring(int startIndex)

Or, alternatively:

.Substring(int startIndex, int length)

[mamtawardhani]

Suggested change

	- `startIndex`: The index from where the substring starts.
	- `Length`: The maximum length of the substring - (Optional).
	- `startIndex`: The index from where the substring starts.
	- `Length` (Optional): The number of characters to include in the substring..

Suggested change

	string str = "Codecademy";
	Console.WriteLine(str.Substring(4));
	using System;
	public class Program
	{
	public static void Main()
	{
	string str = "Codecademy";
	Console.WriteLine(str.Substring(4));
	}
	}

included the code in a class

[mamtawardhani]

Suggested change

	```cs
	```shell

[mamtawardhani]

The output is always wrapped in the shell block

[mamtawardhani]

Suggested change

	string str = "Codecademy";
	Console.WriteLine(str.Substring(2, 6));
	using System;
	public class Program
	{
	public static void Main()
	{
	string str = "Codecademy";
	Console.WriteLine(str.Substring(2, 6));
	}
	}

[mamtawardhani]

Suggested change

	Here, `.Substring()` is used with the optional "Length" value so that it returns a string composed of the 6 characters from index 2.
	In this example, `.Substring()` is used with the optional `length` parameter to return a substring of 6 characters starting from index `2` of the string `"Codecademy"`.

Suggested change

	In this Codebyte example, `.Substring()` is used to return a name without it's initial letter.
	Run the Codebyte example, to understand how the `.Substring()` method works:

Hello.

Thank you for the helpful comments. I'm sorry for the amount of changes, I am rather new to this.

Should I change the file, commit the new changes and do another pull request? or do I change it within Github itself?

You can change it within this PR itself. You should see a "commit suggestion" button wherever I have suggested changes, just click on it and for the comments, you will have to make changes in your local file and push the changes on the same branch. So no new pr is needed 😃
