OOP Calendar Application Creation
Description
This assignment has you creating an OOP Calendar application allowing for the user to create appointments and reminders on a custom calendar.
Programming Assignment:
Instructions:
This assignment gives you a specification for several classes to create to make this Calendar application.
The classes are described in plain language. You are expected to code the classes using good OOP Principles
- Use of data hiding
- Appropriate isolation of knowledge/responsibility
- Creating appropriate getters/setters
- Creating private/protected helper methods if needed
You must create a .h file for your Calendar related classes and an accompanying
.cpp file for those classes’ method definitions
Use of #include
Create a simple numerical menu-driven system to use the calendar.
Sample Output:
Note: You’ll want to make this better, this is just a basic example to show expectations of use.
