'\n' is a single newline character.
"\n" is a string containing only a single newline character.
std::endl is an iostream manipulator that, when inserted into a stream, writes a newline and then flushes the stream.
Use endl if you want a newline and want to force immediate display of the output (or you want to safeguard against data loss in the face of a crash, i.e. when writing debug information).
All other times, in particular when your next operation is writing yet another thing, use the newline character directly.
All the buzzt!

Forcing a stream to flush is rarely necessary in C++, it is almost always done automatically in the cases that you need it. Because of this I almost always use '\n' and if I really want a flush I just send std::flush to the stream instead of std::endl to make it clear that I'm trying to force a flush specifically.
