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.
