Accessing each character of a string

Accessing the individual characters of a string is a common part of any Section B question. This page looks at the different methods you can use to achieve this.

Method 1

1 Console.WriteLine("please enter a word:");
2 string word = Console.ReadLine();
3 		
4 for(int i=0; i < word.Length;i++)
5 {
6 	Console.WriteLine(word[i]);
7 }
8 	
9 Console.ReadLine();

Line 1 & 2 will prompt for the word and store it in a variable called word.

Line 4 is a for loop which will start at zero and continue while `i` is less than the length of the word.

Line 6 uses `i` to access that specific character of `word`. the square brackets `[]` is always about accessing a specific element.

The benefit of using this method is that changes can be made to `word` within this loop.
