probly a simple solution

hi guys,
can someone HELP

I have a class that receives a start date and end date
(ie. as 12 11 2005) and I have to print out the dates in between
in form 12 November 2005.

I have various functions that convert the date etc. but am stuck with defining

operator++

I really can't find any example that shows this.

Here is what I have and the errors:

MY CODE:

Code:

 void date::operator++(date& oldDate)
{
  unsigned maxDaysInMonth, maxDaysInFeb;
  unsigned dayOfMonth=oldDate.getDay();
  unsigned monthOfYear=oldDate.getMonth();
  unsigned myYear=oldDate.getYear();

  if (oldDate.isLeapYear(myYear))
    maxDaysInFeb=29;
  else
    maxDaysInFeb=28;

  switch(monthOfYear)
    {
    case 1: case 3: case 5: case 7: case 8: case 10: case 12:
      maxDaysInMonth=31;
    case 4: case 6: case 9: case 11:
      maxDaysInMonth=30;
    case 2:
      maxDaysInMonth=maxDaysInFeb;
    default:
     break;
    }

  if (maxDaysInMonth=dayOfMonth)
    {
      oldDate.setDay(1);
      if (monthOfYear=12)
        {
          oldDate.setMonth(1);
         oldDate.setYear(myYear+1);
        }
      else
        {
          oldDate.setMonth(monthOfYear+1);
         oldDate.setYear(myYear);
        }
    }
  else
    {
      oldDate.setDay(dayOfMonth+1);
      oldDate.setMonth(monthOfYear);
      oldDate.setYear(myYear);
    }

}

THE Errors:

Code:

date.h:35: error: postfix `void date::operator++(date&)' must take `int' as its
   argument
date.cpp:135: error: postfix `void date::operator++(date&)' must take `int' as
   its argument

I know this would be pretty straight forward but how can i make it work?

thanks

Are you sure in your member function declaration it does not pass a type int?

Also, member functions can access private member variables, you do not have to use a function call to access it.

I am not sure what you mean?
my .h and .cpp have same names...

my private members are
unsigned day
unsigned month
unsigned year

As for accessing private members, I tried to daclare day=oldDay.getDay() but this didnt work!!

In your class, what does the function declaration look like?

As for accessing private members, I tried to daclare day=oldDay.getDay() but this didnt work!!

A class function has access to private member variables.

So instead of this:

Code:

unsigned myYear=oldDate.getYear();

you could just use =oldDate.year;

Unless your getYear/Day/Month function does something besides just return the private member variable.

my member function (if this is what I think it is ) is
date (unsigned newDay, unsigned newMonth, unsigned newYear)

and my default sets day and month to 1 and year to 0000;

Am I even answering the question?

I just cant seem to understand what it means.

I have tried to use
int instead of void, a bool, ostream, but in all honesty, don't get it!!

Thanks for the help, is this a really stupid and dumb question or do I just feel that way?

the function declaration:
(in date.h)

Code:

void operator++(date& oldDate);

Code:

if (maxDaysInMonth=dayOfMonth)
{
    oldDate.setDay(1);
    if (monthOfYear=12)

I hope you mean == and not =.

I will fix this!!

Thanks!!

Will this help compiling?

I have fixed this problem...

Still, my error is:

Code:

date.h:36: error: postfix `bool date::operator++(date&)' must take `int' as its
   argument
date.cpp:162: error: postfix `bool date::operator++(date&)' must take `int' as
   its argument

even though I have changed to a bool fulnction that returns if the received date is valid.

Can anyone see the problem?

I am (obviously) pretty average at this, but I can't do anything else until I fix this code.

Why must it take int as it's argument?

I don't understand. Shouldn't it take true/ false as its argument?
And a postfix: I have tried to declare it as unsigned function... this did not work...

You're trying to pass a variable (bool) when you've voided it....

try this

Code:

bool date::operator++(date& oldDate)

since you're giving it something, when it is voided, its automatically declaring it as an integer...

This may not be true, but tis my speculation


Errrr... I just realized you've declared it as bool date already...


Well, perhaps it wants a 0 or a 1, 1 meaning true, 0 meaning false????

Sorry you lost me :\

I have totally lost me too!!

You are totally right though, when I changed to a bool, the error changed to


# must take either zero or one argument#

Then, I changed it a bit more as

date date:perator++(unsigned newDay, unsigned newMonth, unsigned newYear) and same error!!

Is there anybody who has previously coded something like this?

I am happy to recode the whole thing, but don't even know where to start!!

This thing was due 4 days ago (there goes 40%) and it is just getting impossible to finish.
