WHAT ARE CONSTANTS? AND ITS TYPES:

OK NOW LETS LEARN ON THEORY BASIS WHAT IS CONSTANT.

SO THE TERM CONSTANT REFERS TO THE VALUE OF A VARIABLE WHICH DO NOT CHANGE DURING THE EXECUTION OF PROGRAM.

IN C PROGRAMMING LANGUAGE CONSTANTS IS DIVIDED IN TO TWO TYPES. THEY ARE:

                                             NUMERIC CONSTANT.

                                            NON NUMERIC CONSTANT 

NUMERIC CONSTANT:

                       NUMERIC CONSTANT CAN BE REPRESENTED THROUGH THE FIXED INTEGER NUMBER OR REAL NUMBER.

                         DONT WORRY I KNOW WHAT YOU ARE THINKING NOW I WILL TELL YOU WHAT IS INTEGER AND REAL CONSTANT.

                          OK NOW NUMERIC CONSTANT IS SUB DIVIDED IN TO TWO TYPES.THEY ARE:

                                                      INTEGER NUMBER.

                                                      REAL NUMBER.

INTEGER NUMBERS:

                 IT CAN BE REPRESENTED THROUGH THE WHOLE NUMBERS (0-9).

                 WE CAN REPRESENT OCTAL NUMBERS USING NUMBER (0-7).

                 HEXA DECIMAL CAN BE REPRESENTED BY USING THE NUMBERS 0-9 FOLLOWED BY A-F AND PROCEEDED WITH ox/OX.

REAL CONSTANT:

             REAL NUMBERS IS ALSO KNOW AS FLOATING POINT NUMBERS.

             IT IS USED TO REPRESENT VARYING  MEASUREMENTS  LIKE:

                                                 PRICE.

                                                 TEMPERATURE.

                                                 VOLTAGE.

                                                  ETC.

NON NUMERIC CONSTANT:

                             IT IS USED TO REPRESENT NON NUMBER CONSTANTS WHICH CONSISTS OF ALPHABETS AND STRINGS.

                              THEY ARE CALLED BY THE NAME CHARACTER CONSTANTS AND STRING CONSTANTS.

CHARACTER CONSTANTS:

                       IT CONTAINS ALPHABETS FROM THE ENGLISH LANGUAGE WHICH ARE ENCLOSED WITH SINGLE QUOTE.

STRING CONSTANT:

                       IT IS REPRESENTED BY MORE THAN ONE ALPHABETS FROM ENGLISH LANGUAGE WHICH ARE ENCLOSED WITH DOUBLE QUOTES ARE KNOWN AS SRRING CONSTANT.
