Refactoring/ChangeSignature.cpp

//Use Change Signature (Ctrl+F6 on Windows/Linux, Cmd+F6 on macOS) to:
//- Add another Person Data parameter to the callPerson function.
//- Swap two input parameters in the callPerson function.
//- Use Change Signature to add rate_cf with the default value, use completion for DEFAULT_RATE
//- Extract parameter (extra_cf), check the value from the initializer is used in the usages

#define DEFAULT_RATE 100
