Those are conversion techniques, nothing to do with parsing the
command line. The library code that calls main does the parse.

See http://mindprod.com/applet/conversion.html

It will show you how to convert any of the basic types into any of the
others.  It shows multiple ways sometimes, with notes on the
advantages of each.  In general, the one I consider generally best is
at the top.
