- What are the differences between if-else and else-if? [closed]
IF a condition is true, do something, ELSE (otherwise) IF another condition is true, do something, ELSE do this when all else fails Note that there is no else if construct specifically, just if and else, but the syntax allows you to place else and if together, and the convention is not to nest them deeper when you do For example:
- IF, ELSE IF, ELSE ou IF IF IF. Quando usar, qual a diferença?
As demais respostas já explicam muito bem, mas gostaria de complementar com o seguinte: com frequência existem várias maneiras de se fazer a mesma coisa, sem que exista claramente um "melhor" ou "pior", de modo que cabe a você - pela sua experiência ou pelo seu feeling - decidir qual delas usar caso a caso
