Answer 1

Use comments to insert ASCII art into your source file. :D

Answer 2

lol @hatsy another great idea !

for short statements, variables it's good to use 1st method but when using long comments i believe the 2nd style is better.

but long comments use
/**/

Answer 5

ah @james tedious but what a nice idea !

Answer 6

//for long comments two lines or less. I use a single line comment this way.

/* for bigger comments which span more than 3 lines its better to use multi line comments but does not matter much both work just fine and have not much issues

PS: I hardly write comments bigger than 2 lines . I use this only for commenting big functions, code snippets a little blurb that's all. i have a preference for using
single line comments for convenience sake"// #
