OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Step by step
Solved in 2 steps
- What is the purpose of creating cross-class inheritance relationships?How does the concept of multiple inheritance via interfaces differ from multiple inheritance via classes with respect to code complexity and maintainability?There must be an in-depth discussion and explanation of the concept of inheritance and polymorphism.
- Passing arguments to base classes constructors solves the problem of selecting a base class constructor in inheritance. Can the same problem arise with composition? That is, might there be a case where a constructor of a class might have to pass arguments to the constructor of a contained class? If so, guess the syntax that would be used to pass the parameters, and construct a simple example to verify your guess.The main benefit of inheritance is reusability. What is the main tradeoff (i.e., "cost") of having inheritance? (as compared to a "pure" ADT?) Give an example of an inheritance hierarchy that exhibits this tradeoff. (For example, consider a BankAccount -> CheckingAccount relationship.)When might we expect uncertainty to arise due to multiple inheritance? In what ways may we go about fixing this issue? Can you define virtual base classes for me? If so, why do we care so much about them?
