    The document contains 3 programming tasks involving object oriented concepts in C++. Task 1 defines an Employee class with data members for id and salary. A Manager class is derived from Employee with additional data for manager id and department. Objects are created and data is input and output for the classes. Task 2 defines a base Student class with data for admission details. Derived Undergrad and Graduate classes add a department data member. Student objects are created and data input/output based on class type. Task 3 defines base Mammal and MarineAnimals classes with functions. The BlueWhale class inherits from both bases and overrides a function. Objects are created and parent/child functions are called.
