Explanation of Solution

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 first value the index value will be “0” and to find the last character use “length(variable)-1”.

Example:

//declare and define a string

Declare String txt = "Hai"

Explanation:

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”.

Explanation for the incorrect answer:

Display str[1]:

The above statement is used to display the second character of the “str” string.

Hence, the option “A” is wrong.

Display str[first]:

The above statement is used to display the character present at the value of “first” , ”,(that is the value that variable last holds ) of the “str” string.
