Q3. Types of polymorphism
Ans. 
Types of polymorphism include compile-time polymorphism (method overloading) and runtime polymorphism (method overriding).
• Compile-time polymorphism is achieved through method overloading, where multiple methods have the same name but different parameters.

• Runtime polymorphism is achieved through method overriding, where a subclass provides a specific implementation of a method that is already defined in its superclass.

Q1. What is the concept of virtual inheritance in relation to vtables and vptrs in object-oriented programming?
Ans. 
Virtual inheritance allows a derived class to inherit from a base class without creating duplicate base class subobjects.
• Virtual inheritance is used to resolve the Diamond Problem in C++ where a class inherits from two classes that have a common base class.

• It ensures that only one copy of the base class is inherited by the derived class.

• Virtual inheritance introduces a virtual base class subobject to the derived class,...read more

Q1. What is the implementation of a class for string operations?
Ans.

• Create a class with methods like concatenateStrings, extractSubstring, calculateLength, etc.

• Use string manipulation functions like substring, concat, length, etc. within the class methods.

• Ensure error handling for edge cases like empty strings or out-of-bounds indices.

• Example: class StringOperations { conc...read more

Q1. Interface why we use Basic OOPs Sorting Algo
Ans. 
Interfaces are used in OOP to define a contract for classes to implement, allowing for polymorphism and loose coupling.
• Interfaces in OOP define a set of methods that a class must implement, providing a contract for behavior.

• Interfaces allow for polymorphism, where different classes can be treated as instances of the same interface.

• Interfaces promote loose coupling between classes, as they only need to know about the in...read more
