Multiline Comments

Use multiline comments starting with slash-star and ending with star-slash to document your work. You should put a comment block, for example, at the beginning of each file.

This syntax is the same as in Java and C++.

Example

/* 
  This apple can only be compared to 
  other apples
*/

Load the above code into UmpleOnline

Syntax

multilineComment- : /* [**multilineComment] */
