Tapan Patel · Answer

If you consider the modern compiler optimization techniques, you really won't see a difference but still... switch case - uses branch table/jump table implementation - so if you want to try, you can use the stop watch and see the difference for the code with if-elseif and switch.

BASIS FOR COMPARISON IF-ELSE SWITCH Basic Which statement will be executed depend upon the output of the expression inside if statement. Which statement will be executed is decided by user. Expression if-else statement uses multiple statement for multiple choices. switch statement uses single expression for multiple choices. Testing if-else statement test for equality as well as for logical expression. switch statement test only for equality. Evaluation if statement evaluates integer, character, pointer or floating-point type or boolean type. switch statement evaluates only character or integer value. Sequence of Execution Either if statement will be executed or else statement is executed. switch statement execute one case after another till a break statement is appeared or the end of switch statement is reached. Default Execution If the condition inside if statements is false, then by default the else statement is executed if created. If the condition inside switch statements does not match with any of cases, for that instance the default statements is executed if created. Editing It is difficult to edit the if-else statement, if the nested if-else statement is used. It is easy to edit switch cases as, they are recognized easily.
