Yes, in compiled languages. Compilers often optimize switch statements using Jump Tables, making them O(1), whereas an if-else chain is O(N).
Using Switch Cases vs If-Else Chains
Is switch faster than if-else?
The answer
More FAQs in Using Switch Cases vs If-Else Chains
A switch statement is a control flow mechanism that tests a single variable for equality against a list of predefined cases.
Generally, no. Standard switch statements check for exact equality. For ranges, you must use an if-else chain.
The program will experience 'fall-through'. It will execute the matched case and continue executing all subsequent cases until a break is encountered.
