if you can do it by changing 6 lines in the example and theres a
significnat userbase, why not ?

but i suspect neither is true for INTERCAL

same here, if we could make our examples be useable & valid for these
by changing 6 lines and theres a significnat userbase ...
java and PHP have a significnat user base but i dont think a long
piece of C code would magically turn into PHP or java by chnaging
6 lines

We could add a comment that clarifies that the casts are bad practice
in C but needed to support C++

do you volunteer to maintain a seperate set of
examples for C++.
I would have thought that having the same example code usable for
both languages would be the overall better solution

but iam happy with anything people prefer, the only thing that iam
not happy about is if the average C++ programmer cant use the examples
and that then is only because of 6 lines of code and some
philosophical reasons
