Error C2664!

Freckles1224 (6)
I get an error C2664: 'Process_Data' : cannot convert parameter 2 from 'Stud' to 'Stud []'

:^(


I tried searching the forums before posting and I found that adding another [] to the prototype would normally fix the issue, but it didn't seem to help with my program.

void Process_Data(ifstream, Stud, PStud &, int &);
Second parameter is a Stud object. No, wait...
void Process_Data(ifstream &Input, Stud temp[], PStud &list, int &Num) Second parameter is an array of Stud objects.

Pick one, and stick with it.

so i replaced
void Process_Data(ifstream, Stud, PStud &, int &);
with
void Process_Data(ifstream, Stud[], PStud &, int &);

and added [Size] to the second parameter in my int main
Process_Data(Input, TEMP[Size], Stud, Num);

but now it's telling me that my "Process Data" is wrong:
IntelliSense: no instance of overloaded function "Process_Data" matches the argument list

and I still have error c2664
:^(
Moschops (7244)
Process_Data(Input, TEMP[Size], Stud, Num);

The second parameter should be an object of type Stud[]. TEMP[Size] is not such an object. TEMP is.

It's much easier to use proper C++ vectors for this sort of thing.

Thanks for your help so far, my professor didn't have time to go over vectors this semester.

Ok, so when I use
Process_Data(Input, TEMP, Stud, Num)

I no longer get c2664, but I still get
IntelliSense: no instance of overloaded function "Process_Data" matches the argument list

and now
error C2248: 'std::basic_ios<_Elem,_Traits>::basic_ios' : cannot access private member declared in class 'std::basic_ios<_Elem,_Traits>'

how would I make the member public?
