Question

C++ has std::endl. Does anyone know of anything in C to use for this?

Answer 1

std::endl has the effect of printing a newline '\n' character and then flushing the output stream.

The C equivalent, if you’re printing to stdout, would be:

putchar('\n');
fflush(stdout);

But in most cases the fflush is unnecessary.

Note that std::endl does not have the purpose of providing a platform-independent line ending. The character '\n' already is a platform-independent line ending. When written to a text stream, it will be translated to whatever line ending the platform uses (\r\n for Windows, just \n for Unix, etc.).
