If we have definition /declaration of a function in base class and want to have a definition of same function name in derive class and want to call derived function using base class pointer, then we need to override function. NOTE: As per question criteria, we will write code using interface, but, to describe the concept a basic example will be covered first.įunction overriding concept is run time polymorphism in oops, in which functions get resolved on run time using VTABLE (Virtual table) by compiler. You need to prepare for the interview thoroughly to clear the technical interview. We are preparing the list of questions from the entry level to the advanced level.
#Oops interview questions software#
If you follow best coding practice and the things you care when write the code. As we know OOPS are the more common technology with more openings in the Software and hardware industry.You know the concept and syntax of function overriding in C++.Take example of drawing multiple shapes e.g.
Explain the concept of function overriding.Show the function call in main program.Write a complete class stating function overriding feature in C++.Inheritance provides code reusability, makes it easier to create and maintain an application.
Ans: Inheritance allows One class to gain all the members(say attributes and methods) of another class. C++ Technical Interview Question on polymorphism in oops Explain Inheritance in Python with an example.
