The C++ compiler must know that f(int,char,float) is to be called by a C compiler using the extern “C” construct:

The extern “C” line tells the compiler that the external information sent to the linker should use C calling conventions and name mangling (e.g., preceded by a single underscore). Since name overloading isn’t supported by C, you can’t make several overloaded functions simultaneously callable by a C program.
