How o write glsl remark?

Does it like c/c++ to remark its statement followed with symbol " // ? or ? // "?

Rather than give you a fish, I’ll teach you.

Go here:

Specifically, look at the “GLSL Specification”:

Search for “Comment”. Then click on the hot section link with that name that comes up in the Table of Contents.

omments are delimited by /* and */, or by // and a new line. Totlally same as that in C. just a word." same".
Fishing is good than giving a fish, but need too much time.
thank u .
