See more:

as I was writing a code for my project ,the compiler gave me this error message
'enterDoctor' : 'static' should not be used on member functions defined at file scope
where (enterDoctor) is a public member function which I need it to be static.
I tried to upload the source code "it's not big:thumbsup:" but I didn't know how ,so I'll post the most important instruction .
in the header file 'Doctor.h'

public:<br />
static void enterDoctor(char*&,char*&,char*&,float&);

the implementation 'Doctor.cpp'

static void Doctor::enterDoctor(char*&fName,char*&lName,char*&ad,float &fee){
	cout<<"enter first name : ";cin>>fName;
	cout<<"enter last name : ";cin>>lName;
	cout<<"enter address : ";cin>>ad;
	cout<<"enter fee : ";cin>>fee;
	}

so.....what do think ????? where is the problem !!!!!

If you are in this position, you'll probably also have a "doctor.h" containing the class declaration looking like this:

class Doctor
{
    ...
public:
    static void enterDoctor(char*&fName,char*&lName,char*&ad,float &fee);
    ...
};

Now, in your CPP file, to define the body of this function, you don't need anymore to say it is static (static at file level means a different thing than at class level).
Just declare it as

void Doctor::enterDoctor(char*&fName,char*&lName,char*&ad,float &fee)
{
 ...
}

Note that virtual member functions also have this kind of problem.
