[Dev-C++] need help on converting a phone number

[Alan T. <ala...@3n...>]

    Are you just in C or C++?  strtok is a terrible function, because it
destroys the original string by placing a NULL character at the location of
the delimiter.  So, if you use it, you should copy the original string into
a temporary one.  See http://www.gator.net/~garyg/C/FUNCTIONS/strtok.html
for info on the function.

            If you can use C++, there are some nice string operations (find,
substr, etc.) to do things like this easily.  You could read it in as a
string, find a delimiting character (or string or from a set of characters)
and extract a substring, without messing up the original string.  This is a
much cleaner implementation.  See
http://www.icce.rug.nl/docs/cplusplus/cplusplus.html for a tutorial on these
string operations -- find the string section.
