Calendar project in c and c++ Solved
In this project, we design calendar with graphics using C language under Turbo C++ compiler. Calendar designed here has many features like display current time, jumping to a particular date, to a particular month, check day on a particular date etc.
Here we use Turbo C++ compiler because it support both C and C++ and also support graphics which is most important for designing games and other utility application.
Data validation:
We have written many codes for data validation that is most important in calendar design. Code for data validation includes:
1. Data validation for normal and leap years.
2. Number of days in a month for different months for a normal and leap year.
3. Data validation for time.
Most important term in calendar design is leap year. If we not take leap year correctly then we never get correct output.
Condition for leap year:
For century years: century year must be divisible by four hundred (400) for a leap year i.e. year 2000 is leap year while 1900 is not a leap year.For non-century years: non-century years must be divisible by 4 for a leap year i.e. 2004 is leap year while 2011, 2014 is not a leap year.

Run this program using TURBO C++ compiler. You can also manipulate code for different looks and output and to add or delete some features.
Here we use Turbo C++ compiler because it support both C and C++ and also support graphics which is most important for designing games and other utility application.
