Question: Why doesn’t anyone use single-line comments?

the /* */ doesn’t nest.

Like:


//This is a one line Comment.

/* Commented_Out_Code();
 /* this is a multi-line
     Comment in Code */
 This_Code_Still_Executes(); */

/* Commented_Out_Code();
 // this is a multi-line
 // comment in code
 // split into single-line
 // comments
 This_Code_Dont_Execute(); // :ahh:  */

The reason I say this is that you can use /* */ for commenting out and debugging.

Isn’t it good coding practice to do this anyway?

Plus, It isn’t in the default code, Anywhere.

The way I’ve always understood it was that /* */'s were the only way to use comments in C. When C++ came along, it added the // style comments. Therefore: //'s aren’t a part of standard C, only C++.

That probably explains why a lot of people don’t use them: they don’t expect them to work! However, you are correct in saying that the Microchip compiler does seem to allow them.

So // away!

I have wondered the same thing. It gets quite annoying trying to comment out blocks of code that contain multiline comments.

#4

It would seem like Whoever wrote the default code would know about //. :shrug:

I actually got the idea from NQC, a C-like language for LEGO’s RCX :]

#5

my standard practice is to make comments that actually say something single-liners “//”, and use “/* */” for commenting out blocks - that way there is no conflict.
