why do we use // in c++ ?

Answer 1

thanx. I know it was a silly question but this is my first time learning any computer language so yeah I asked a stupid question. thank u so much for helping though:)

Answer 2

I'm not sniping at the answer; I see what's accepted. This answer is for a computer history worksheet meaning: "why C++ has // and C does not", otherwise it's social [trivia] ~ how popular convention becomes standards.

From source*:
"// comments were added for C99 due to their utility and widespread existing practice, especially in dual C and C++ translators."

[Early programmers used line editors (EDLIN is still in Win10, 32-bit) where // was more important; you can still find old posts from people who preferred one style over another]
