## Description
|
||
<section id='description'>
|
||
<code>if/else</code> утверждения могут быть объединены вместе для сложной логики. Вот <dfn>псевдокод</dfn> операторов с несколькими цепями <code>if</code> / <code>else if</code> : <blockquote> если ( <em>условие 1</em> ) { <br> <em>statement1</em> <br> } else if ( <em>условие2</em> ) { <br> <em>оператор2</em> <br> } else if ( <em>условие 3</em> ) { <br> <em>оператор3</em> <br> , , , <br> } else { <br> <em>statementN</em> <br> } </blockquote>

## Instructions
