Q1. What is a constructor in C++?
Ans. 
A constructor in C++ is a special member function that is automatically called when an object is created.
• Constructors have the same name as the class and do not have a return type.

• They can be used to initialize the object's data members.

• Default constructors are automatically generated if no constructor is defined.

• Parameterized constructors can be defined to accept arguments during object creation.

• Copy assignment operator is denoted by the = operator.

• It is used to copy the values of one object into another object of the same class.

• It is automatically generated by the compiler if not explicitly defined.

• Example: MyClass obj1; MyClass obj2; obj2 = obj1; // Copy assignment

Q3. What is virtualization in C++?
Ans. 
Virtualization in C++ is the process of creating a virtual version of a class or function to allow for polymorphism and dynamic binding.
• Virtualization in C++ is achieved through the use of virtual functions and inheritance.

• Virtual functions are declared in a base class and overridden in derived classes to provide different implementations.

• Virtualization allows for polymorphism, where a pointer to a base class can point...read more

Q5. What is smart pointers?
Ans. 
Smart pointers are objects that act like pointers but provide automatic memory management.
• Smart pointers help prevent memory leaks by automatically deallocating memory when no longer needed.

• Examples include unique_ptr, shared_ptr, and weak_ptr in C++.

• They provide better memory safety compared to raw pointers.
