10 Frequently Asked Questions (FAQs) on Above Topics with Answers:

1. Q: What is a pointer in C++ and how is it used? A: A pointer is a variable that stores the memory address of another variable. It's used for dynamic memory allocation, accessing arrays and strings, and more.

2. Q: How does inheritance work in C++? A: Inheritance allows a class (derived class) to inherit attributes and methods from another class (base class), promoting code reusability and polymorphism.

3. Q: What is a virtual function? A: A virtual function is a member function declared within a base class and redefined by derived classes. It's used to achieve runtime polymorphism.

4. Q: Can constructors be private in C++ and why? A: Yes, constructors can be private, usually in singleton patterns to control object creation.

5. Q: What are templates in C++? A: Templates allow functions and classes to operate with generic types, enabling code reusability for any data type.

6. Q: What is the difference between 'new' and 'malloc'? A: 'new' initializes objects, calls constructors, and is an operator. 'malloc' only allocates memory, doesn't call constructors, and is a function.

7. Q: How does exception handling work in C++? A: Exception handling in C++ is done using try, catch, and throw blocks to handle errors gracefully.

8. Q: What is the use of the STL in C++? A: The Standard Template Library (STL) provides a set of common classes and interfaces for data structures and algorithms.

9. Q: What is the difference between a structure and a class in C++? A: The primary difference is in access control: class members are private by default, while structure members are public.

10. Q: What is a smart pointer and why is it used? A: Smart pointers are template classes that ensure automatic memory management to prevent memory leaks. They handle the object lifecycle and resource deallocation.
