The thing that you need to know about the difference between a scripting 
language and C/C++ is that the later is strongly typed.

This means that you basically need to know what these types are and what 
can and can't be auto converted.

In your case, you are treating a *char as an int.

If you are using C++, the most eligant way to do this is via 
boost::lexical_cast.  In C, there are more primative facilities.  Look 
for atoi documentation.
