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
- 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.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?
- 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.)There must be an in-depth discussion and explanation of the concept of inheritance and polymorphism.It is necessary to provide an explanation of both the concept of inheritance and the links between the objects.
