I was under the impression that cout and cin for I/O was actually _faster_
than using printf.  I thought this was because printf must parse
the format string each time to determine how the subsequent parameters
are to be interpreted and output, whereas this is done at compile time
for cout.  The format string is typically constant but must be reparsed every
time the printf function is called, which doesn't sound very efficient to me.
What is the logical argument for printf being faster?

If anyone has any numbers on stream I/O vs printf, I'd be interested in
hearing them.
