  The C character set

                                                      A character is a part of a word, sentence or paragraph. By using different character, words, expressions and statements can be created on the basis of the requirement. This creation depends upon the computer on which a program run. 
                                                                 A character is represented by any alphabets in lowercase or uppercase, digits or special characters. Figure presents valid categories of C character set, which are follow: (i) letters, (ii) digits, (iii) white space and (iv) special characters.
                         

     The character list in the given table are represented in the computer by numeric values. Each character is assigned a unique numeric value. The value put together are called character code. which are used in the computer system. The widely used computer codes are ASCII and EBCDIC.

   
    ASCII Code : ASCII stands for American Standard Code for Information Interchange. is the code are of two types. One uses 7 bit and other uses 8 bit. The 7-bit code represent 128 different characters and the 8-bit code represents 256 characters. For example the character A is represented in 7-bit code as 0000000-11111111.

String Comparisons

-
The String class provides the methods for comparing strings, as given below:-                       Method                                                            Defination str2.equals(s1: String): boolean                        Returns true if this string is equal to string s1. str2.equalsIgnoreCase(s1: String): boolean      Returns true if this string is equal to string s1 case                                                                                   insensitive. str2.compareTo(s1: String): int                        Returns an integer greater than 0, equal to 0, or less                                                                                 than 0 to indicate whether this string is greater than,                                                                                 equal to, or less than s1. str2.compareToIgnoreCase(s1: String): int      Same as compareTo except that the comparison is case
