hi friends

can anyone help me understand this question:-

Define a class called Month. Your class will have one attribute of type int to represent a month (1 for January, 2 for February, and so forth). Include all the following methods in this class:
a) a constructor to set the month using the first 3 letters in the name of
the month as 3 arguments ('J' 'A' 'N' for January, 'F' 'E' 'B' for
February and so forth),
b) a constructor to set the month using an integer as an argument (1 for
January, 2 for February and so forth),
c) a default constructor,
d) an input function that reads the month as an integer,
e) an input function that reads the month as the first 3 letters in the
name of the month,
f) an output function that outputs the month as an integer,
g) an output function that outputs the month as the first 3 letters in
the name of the month,
h) and a member function that returns the next month as a value of type
month.

Test your class in a new program which has the main () method.

Thanks in advance..
