Difference Between cout << "Hello\n"; and cout << "Hello" << endl;

Question:
What is the difference between cout << "Hello\n"; and cout << "Hello" << endl;?

Answer:
The C++ ANSI draft standard defines the charecter literal \n as the new line (or linefeed) character. This also corresponds to the end-of-line char in many platforms (at least in all platforms I have used). This need not be true on all platforms, though. Thus, using endl is a good practice from the portablity point of view.
