C++ Interview Questions

What are some common C++ interview questions I should prepare for?

Some common C++ interview questions include:

1. What is the difference between C++ and C?
2. Explain the concept of polymorphism.
3. What are constructors and destructors?
4. How does memory management work in C++?

Can you explain polymorphism in C++?

Polymorphism in C++ allows methods to do different things based on the object it is acting upon. It can be achieved through function overloading and operator overloading, as well as through inheritance using virtual functions.

What is the purpose of constructors and destructors?

Constructors are special member functions that are called when an object is created, used to initialize the object. Destructors are called when an object is destroyed, used to free resources allocated to the object.

How does memory management work in C++?

Memory management in C++ involves allocating and deallocating memory using operators like 'new' and 'delete'. It requires careful handling to avoid memory leaks and dangling pointers.
