Program Plan Intro

Character by character text processing:

• Strings can be accessed or manipulated by using an individual text that is present.
• Different programming language access the string individually in a different way, some prefer the string gets accessed through subscript notation.
• String is considered as list of characters.

Accessing string using subscript notation:

• The string that are accessed using the subscript notation uses subscript “0” to hold the first character and similarly till the last character.
• The last character of the string will be “\0”.
• The first value the index value will be “0” and to find the last character use “length(variable)-1”

//declare and define a string

Declare String txt = "Hai"

In the above declaration, the given string  gets processed in the following way:

txt[0] will hold “H”.

txt[1] will hold “a”.

txt[2] will hold “i”.
