Is there a benefit from endl or /n

Question

what's the difference between the two because they do the same thing?

Answer 1

from what I've just read on stack the endl manipulator flushes the stream buffer, the \n doesn't.

Answer 2

using "\n" in your string makes it weird. so endl just prints another "\n" for you without making it weird.

Answer 3

usage of "\n" :
cout << "some string\n";
// (weird string / annoying)

usage of endl :
cout << "some string" << endl;
// (better and clean)
