  There's merit in those C functions, though: They are much more efficient
than using stringstreams. (For one, they parse the string *in place*,
rather than copying the string around in memory.)

  Of course their usage is more difficult.

  Another C function can be used to both parse an integer from a string
and know if there was one: strtod(). However, its usage is even more
complicated than atoi().
