What are the differences between switch and if-else in C++?

What are the differences between switch and if-else in C++?

The main differences are in syntax, performance, and use cases. Switch is generally cleaner for multiple discrete values, while if-else is more flexible for complex conditions.

Can you give an example of when to use switch over if-else?

Sure! Use switch when you have a variable that can take multiple specific values, like menu options. If-else is better for ranges or complex conditions.

Are there any limitations to using switch?

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

Is there a performance difference between the two?

In many cases, switch can be faster than if-else, especially with many cases, as it can be optimized into a jump table by the compiler.
