CHARACTER SET

CHARACTER SET

            Instructions in C language are formed using syntax and keywords. Like any other language, C has it’s own vocabulary and grammar. It is necessary to strictly follow C language Syntax(grammatical) rules. These Syntax were maid using some symbols and words. Any instructions that mis-matches with C language Syntax generates an error while compiling the program. 

            The character set in C Language can be grouped into the following categories.

1. Letters                     a to z, A to Z
2. Digits                      0 to 9
3. Special Characters  ,   .   ;   :   ?   ‘   “   !   /   \   ~   -   %   &   |   ^   +   _    *

<   >   (   )   [   ]   {   }   #   =

4. White Spaces          Blank Space, Horizontal Tab, Carriage Return, New Line, Form- Feed

The compiler ignores the white spaces unless they are part of string constant. White spaces are used to separate words, but should not be used between the characters of keywords and identifiers.
