Thread: simple help!! I am failing with CLASS

HI GUYS
I am in big trouble!!

I have so many problems it is hard to know where to begin. Firstly, I will show code:

Code:

#include <iostream>
#include <fstream>
#include <string>
#include <cassert>
#include <iomanip>
#include "date.h"
using namespace std;

int main()
{
  date temp1;
  temp1.setDay(2);
  temp1.getDay();
  cout << temp1 << endl;
}

I have not yet attempted to link this to my library function, just trying to see if this works first...

I am not sure because I am very naive with this but think that it is the way I am trying to compile it.

This method has worked for me in the past.

Is there anything wrong with the actual code?

Here is a brief (compared to the huge running list of error msg) idea of what happens when I compile by

Code:

g++ myProgram.cpp -c

The errors:

Code:

assign5.cpp: In function `int main()':

Any ideas appreciated

You need to define a operator<< for your date class. Put this inside your class defination:

Code:

friend std::ostream& operator<<(std::ostream&, const date&);

And then with your other function definations you'll have to define it. It'll be something like:

Code:

std::ostream& operator<<(std::ostream& o, const date& d)
{
  return o << d.month() << '/' << d.day() << '/' << d.year();
}

or however you want to format it.

Thankyou!! I Will Try Now

It compiled!! Thankyou so much!! Of course, it is not doing what it should, but that I can figure out!!
