multiple files

[poohbear]

the functiondate.cpp is not compiling . these are 3 multi files . can someone help me why its not working

header file 
#include <iostream>

#include <iomanip>

using namespace std;

class Date        //class called date

    {
 private:
  int month, day, year;

 public:
  Date()   //default constructor

  {
    month = 1;

    day = 1;

    year = 2000;
  }

  Date(int d, int m, int y)  //parametized constructor

  {
    day = d;

    month = m;

    year = y;
  }
bool setDate(int, int, int);
        void getDate(int&, int&, int&);
        void printShort();
        void printLong();
        bool isEqual(Date);
        void increment();
        void decrement();
};

All your class functions are missing Date:: on their name

the functiondate.cpp is not compiling

Did you try to compile it? Try to compile it, and tell us what happens.

[poohbear]

it says error extra qualification Date:: on member setDate.
i tried in in the class function prototype and also in the function cpp files and it does that

[Peter87]

You should only prefix the member function names with Date:: when defining them outside the class definition in datefunction.cpp.

thank you , it works
