Comments in lines

Question

Do the slashes only make a single-line comment? What if I have several lines of comments to write? Are there any ways besides just adding two slashes at the beginning of every line?

Answer 1

Oops sorry I've found the answer by myself through learning the course. It begins with /* and ends with */ at the end of the comment block.

Answer 2

you can use // for a single line comment. the one with asterisk for a multi line comment.
