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

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

Some best practices include using initializer lists, avoiding unnecessary overhead, and ensuring constructors are explicit.

Can you explain why initializer lists are important?

Initializer lists are important because they allow you to initialize member variables directly, improving performance and avoiding default construction.

What about default constructors? When should I use them?

Default constructors are useful when you need to create objects without providing initial values. They can also be implicitly called.

Are there any common pitfalls to avoid with constructors?

Yes, common pitfalls include forgetting to initialize member variables, using unnecessary copies, and not handling exceptions properly.
