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

What are some common mistakes when 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 in C++ only works with integral types like int, char, or enum. Using other types will result in a compilation error.

How can I properly handle the default case?

The default case should be placed at the end of the switch statement to handle any values not explicitly covered by the cases.

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.
