Need some help with my operator overloading

mattig89ch (65)
Hello everyone,

I have a hw assignment where I have to take a program I've already done, and overload the increment decrement operators.

Now My teacher gave me a cheat sheet in terms of overloading, but I have no idea how I'm supposed to take that sheet sheet and apply it to this program.

Here is my class atm:

1
2
3
4
5
6
7
8
9
10
11
12
13
14

28
 
#ifndef dateType_H
#define dateType_H 
  
class dateType
{
public:
    void setDate(int month, int day, int year);

    int getDay() const;

    int getMonth() const;

    int getYear() const;

    void printDate() const;

	bool isLeapYear(int year);

	dateType(int month = 1, int day = 1, int year = 1900);

private:
    int dMonth;   //variable to store the month
    int dDay;     //variable to store the day
    int dYear;    //variable to store the year
	int monthMax; //variable to store the max days in the entered month
};

#endif


And heres my implementation:
1

void dateType::setDate(int month, int day, int year)
{
	int maxDays = 0;
		
	if (year > 1699 && year < 4000)
	{
		dYear = year;
	}
	else
		dYear = 2014;
		

	if (month > 0 && month < 13)
	{
		dMonth = month;
	switch (month)
	{
	case 1:
	case 3:
	case 5:
	case 7:
	case 8:
	case 10:
	case 12:
		maxDays = 31;
		break;
	case 4:
	case 6:
	case 9:
	case 11:
		maxDays = 30;
		break;
	case 2:
	{
			  if (isLeapYear(year) == true)
				  maxDays = 29;
			  else
				  maxDays = 28;
			  break;
	}
	default:
		dDay = 31;
	}
	}

	if (day < 1 || day > maxDays)
		dDay = 1;
	else
		dDay = day;

	cout << "There are a maximum of " << maxDays << " This month" << endl;

	monthMax = maxDays;

}

int dateType::getDay() const 
{
    return dDay;
}

int dateType::getMonth() const 
{
    return dMonth;
}

int dateType::getYear() const 
{
    return dYear;
}

bool dateType::isLeapYear(int year)
{
	if (year % 4 != 0) {
		return false;
	}
	else if (year % 400 == 0) {
		return true;
	}
	else if (year % 100 == 0) {
		return false;
	}
	else {
		return true;
	}
}

void dateType::printDate() const
{
	cout << "The date you entered is:" << endl;
    cout << dMonth << "/" << dDay << "/" << dYear << endl;
}

    
dateType::dateType(int month, int day, int year) 
{ 
	
}


I know this applies somewhere:

className operator++();
className className::operator++()
{
this.memberVariable++;
return *this;
}

But I have no idea where I'm supposed to put everything.

I did experiment with putting

 
 
dateType operator ++;


in my class, but when I put
1
2
3
4
5
 
dateType dateType::operator++()
{
	this.dDay++;
	return *this;
}


in my implementation it started throwing all kinds of errors. I'm so very lost with this.

Anyone out there know what I'm doing wrong?

What errors?

operator name needs to be declared as a function

and this needs to be on a non-static number.
