help with additional cpp/header files

[symbit]

I'd like to implement a function from SolsticeClass.ccp into main.cpp by first prototyping it in SolsticeClass.h inside the class, and then creating an object. However, I don't know how to correctly write the function out before prototyping it. The constructor works perfectly fine, though.

  Here's main .cpp:

#include <iostream>
#include "SolsticeClass.h"
using namespace std;


int main()
{
    SolsticeClass s;
s.saying();

    return 0;
}

Here's SolsticeClass.cpp:

#include "SolsticeClass.h"
#include <iostream>
using namespace std;

SolsticeClass::SolsticeClass()
{
cout << "Hello from the constructor!" << endl;
}
void saying()
{
cout << "Hello from the other function!" << endl;
}

and finally, SolsticeClass.h:

#ifndef SOLSTICECLASS_H
#define SOLSTICECLASS_H


class SolsticeClass
{
    public:
        void saying();
        SolsticeClass();

};

#endif

The error message it gives me is as follows:

undefined reference to 'SolsticeClass::saying()'

In your source file just write the function like you did the constructor, i.e.:
void SolsticeClass::saying()

[JLBorges]

// void saying()
void SolsticeClass::saying()
{
    cout << "Hello from the other function!" << endl;
}

Shouldn't saying() be a const member function?

Awesome, thanks guys :)
Didn't know the return type needed to be before the scope operator thing.
