Simple. \n when you just want a newline.
endl when you need to flush at the moment.

Useful in case you are printing a debug output right before some function that might do bed stuff to buffers.

Edit: I wrote println instead of endl somehow. Guess I need more downtime

I only program in C. I was under the assumption that \n also flushes

It depends on whether you are printing to a terminal or to a file (and yes the terminal is also a file), and even then you can control the flushing behaviour using something like unbuffer

I remember having to fflush a couple of times.
