Initializing member variables ensures that they have a defined state before use, preventing undefined behavior and bugs.

What happens if I forget to initialize a member variable?

If you forget to initialize a member variable, it may contain garbage values, leading to unpredictable behavior in your program.

Are there best practices for writing constructors?

Yes, best practices include using initializer lists, providing default constructors, and ensuring exception safety.
