What are the best practices for using switch-case in C++?

Some best practices include using enums for case labels, ensuring all cases are covered, and avoiding complex expressions.

Why should I use enums instead of integers?

Enums improve code readability and maintainability, making it clear what each case represents.

Can you give an example of a switch-case with enums?

Sure! Here's a simple example:

enum Color { RED, GREEN, BLUE };
Color myColor = GREEN;

switch (myColor) {
    case RED:
        // handle red
        break;
    case GREEN:
        // handle green
        break;
    case BLUE:
        // handle blue
        break;
}

What should I do if I have many cases?

If you have many cases, consider using a lookup table or a map to simplify your code and improve performance.
