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. 
A class for string operations can include methods for concatenation, substring extraction, length calculation, etc.
• 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. What is copy constructor?
Ans. 
Copy constructor is a special type of constructor which creates a new object as a copy of an existing object.
• Copy constructor is used to initialize a new object as a copy of an existing object.

• It takes an object of the same class as a parameter.

• It is called automatically when a new object is created from an existing object.

• Example: class MyClass { public: MyClass(const MyClass& obj) { // copy constructor logic } };

Q2. Difference between copy constructor and assignment operator
Ans. 
Copy constructor is used to create a new object as a copy of an existing object, while assignment operator is used to assign values from one object to another.
• Copy constructor is called when a new object is created from an existing object, while assignment operator is called when an existing object is assigned values from another object.

• Copy constructor creates a new object with its own memory space, while assignment o...read more

Q3. What is static function
Ans. 
A static function is a function that is associated with a class rather than an instance of the class.
• Static functions can be called without creating an instance of the class.

• Static functions are commonly used for utility functions that do not require access to instance-specific data.

• Static functions are declared using the 'static' keyword in many programming languages.

• Example: 'Math.max()' in JavaScript is a static fun

Q5. What is single ton design pattern
Ans. 
Singleton design pattern ensures a class has only one instance and provides a global point of access to it.
• Ensures a class has only one instance

• Provides a global point of access to that instance

• Commonly used in scenarios where only one instance of a class is needed, such as database connections or logging

Q1. What is the concept of Object-Oriented Programming (OOP) in Python?
Ans. 
Object-Oriented Programming (OOP) in Python is a programming paradigm based on objects and classes to structure code effectively.
• Encapsulation: Bundling data and methods that operate on the data within one unit (class). Example: class Dog with attributes and methods.

• Inheritance: Mechanism to create a new class using properties of an existing class. Example: class Bulldog inherits from class Dog.

• Polymorphism: Ability to...read more
