Difference between \n and endl?

Question

As I understand \n means a new line and endl means end of the line.I have read somewhere that using endl(stream manipulator) is advantageous.Which one should be preferred and when?

Answer 1

The only difference is that std::endl flushes the output buffer, and '\n' doesn't. If you don't want the buffer flushed frequently(performance issue) then use '\n'

Answer 2

std::endl also flushes the stream it's put on, while '\n' doesn't.

Depends on what you want, to judge which is better to use.

Answer 3

\n merely ends the line. endl ends the line and also flushes the output stream. endl is advantageous when you explicitly care about flushing your output buffer.
