Question

Answer 1

flush == written out to the physical output device

=

The endl manipulator give you a simple way to flush an output stream.

Answer 2

Data streams are often handled in fixed size blocks, data does not always come in convenient sizes.



Example:

say your block transfer size is 5 and your data is 13 in length then the first two blocks of 5 would be transferred but the last three would remain in the buffer waiting for 2 more. As the end of the data has been reached the endl tells the system to process these remaining 3 without waiting for more.

Answer 3

It forces the program to output everything in the output buffer. (Output is placed into a buffer - characters aren't sent out the instant that part of the code is executed - that would slow things down considerably.)
