May I add a question, because cricket uses the underline character. I
know in C++ names staring with 2 underline characters or with one

I believe this applies to property and method/message names only:
Apple reserves them. [...]
Well, the rules about reserved names from ANSI-C would also apply to
ObjectiveC, and those rules from C++ would apply to ObjectiveC++.
As correctly stated, the names are reserved for libraries -- for
example there is nothing preventing strlen to be a macro which
introduce variables, and thus these would (w/o the convention) clash
with the users names.
In C++ there is also the problem of name-mangling, i.e. the compiler
will change names of functions etc. (to allow overloading), and it must
ensure that the user cannot construct a name identical to the result of
some mangling, since that would give linker problems.
