What the heck is endl???
std::endlis used in output streams in C++ to end the line, using the os specific line termination sequence, and flush the buffer.The later one is a performance issue in many cases, why the use of
"\n"is considered preferredDon’t most terminals flush the buffer on newline anyway?
It is the stream itself that is buffered, so the terminal does not handle the contents until the stream is flushed.
