When should I use switch-case in C++?

You should use switch-case when you have multiple discrete values for a variable and want to execute different code based on those values. It's often cleaner and more efficient than using multiple if-else statements.

Can you give me an example of switch-case in C++?

Sure! Here's a simple example:

int day = 3;
switch(day) {
    case 1:
        cout << "Monday";
        break;
    case 2:
        cout << "Tuesday";
        break;
    case 3:
        cout << "Wednesday";
        break;
    default:
        cout << "Invalid day";
}

What are the advantages of using switch-case?

The advantages include better readability, easier maintenance, and potentially faster execution compared to multiple if-else statements, especially when dealing with many conditions.

Are there any limitations to using switch-case?

Yes, switch-case can only evaluate integral types (like int or char) and cannot handle ranges or conditions like if-else can.
