Re: [Dev-C++] linker error

[Per W. <pw...@ia...>]

You must make sure that the file Prototypes.cpp (strange file name by the
way since it doesn't contain function prototypes but actual
implementations...) has been added to the project. If not, the compiler
will not compile it (no Prototypes.o generated) and the linker will not
link it.
