Appendix B -- Ios Manipulators Used with << Operator

These manipulators are used with cout along with the rest of the output varaibles. For example
cout << endl;
ends the line, can be used even after many other outputs
(cout << "Hi!" << endl;)

A short explanation of flush: cout.flush() and cout << flush do the same thing. On some compilers, the output is "line buffered," which means nothing is displayed until an endl or flush is reached -- this is to increase text speed. If output needs to be displayed without ending the line, use << flush or cout.flush() command.
