What are some common mistakes in using switch-case in C++?

What are some common mistakes in using switch-case in C++?

Some common mistakes include forgetting to use break statements, using non-integer types, and not handling the default case.

Can you explain why forgetting break statements is a problem?

Forgetting break statements can lead to fall-through behavior, where execution continues into the next case, which may not be intended.

What happens if I use a non-integer type in a switch-case?

Switch-case statements in C++ only work with integral types like int, char, or enum. Using other types will cause a compilation error.

How can I effectively handle the default case?

The default case should be used to handle unexpected values. It's a good practice to include it to ensure your program behaves predictably.

Are there any best practices for using switch-case?

Yes, always include a default case, use break statements, and consider using enums for better readability.
