What are the best practices for exception safety in programming?

Exception safety refers to the guarantees a function provides when exceptions are thrown. Key practices include using RAII, ensuring strong exception safety guarantees, and avoiding resource leaks.

Can you explain RAII and how it helps with exception safety?

RAII stands for Resource Acquisition Is Initialization. It ensures that resources are properly released when an object goes out of scope, preventing leaks even if an exception occurs.

What are strong and weak exception safety guarantees?

Strong exception safety guarantees mean that if an exception is thrown, the program state remains unchanged. Weak guarantees mean that some changes may occur, but resources are still released.

How can I implement these practices in my code?

You can implement these practices by using smart pointers in C++, try-catch blocks for error handling, and ensuring that your destructors clean up resources properly.
