INTRODUCTION
The project of CSE202 is calendar. I have to prepare a software in which we
have to print the month calendar and day of the specific date. This software is
programmed in Turbo c ++. The software is basically designed to print calendar.
This software is very useful for all the sectors. More over this type of software
is very much used today in cell phones and computers etc.
I have used linking of programs in my project. I have made 6 programs for
different operations and then I have linked them all in my 7th program. And after
that I have linked the 7th program to my main program. So all together 7
programs have been linked with the main program. I have declared the variables
globally and then they have been used in all the class.
