What are the best practices for using constructors in C++?

Some best practices include using initializer lists, avoiding unnecessary constructors, and ensuring proper resource management.

Can you explain why initializer lists are important?

Initializer lists are important because they allow you to initialize member variables directly, improving performance and ensuring proper initialization.

What should I avoid when writing constructors?

Avoid using default constructors when not needed, and be cautious with resource allocation to prevent memory leaks.

How can I implement a copy constructor?

A copy constructor can be implemented by defining a constructor that takes a reference to an object of the same class and copies its members.
