Problem with class.

SlenderMan (69)
I have this code where I need to add the inches and feet together to 1 number. I have to use int CDistance::add(const CDistance&) const to do it though. But when I have this I can't put d1.add() in main. Now when I take out const CDistance& total) it works. How do you do it with the whole thing in there?

  #include <iostream>
#include <conio.h>
using namespace std;

class CDistance
{
private:
		int feet, inches;
public:
		CDistance();
		CDistance(int, int);
		~CDistance();
		void setDist();
		void printDist() const;
		int add(const CDistance&) const;
		int subtract(const CDistance&) const;
};

CDistance::CDistance(int f, int i)
{
	feet = f;
	inches = i;
}

CDistance::~CDistance() {}

void CDistance::setDist()
{
	cout << "Enter the distance. Feet then inches: ";
	cin >> feet >> inches;
}

void CDistance::printDist() const
{
	cout << "Feet: " << feet 
		 << " Inches: " << inches << endl;
}

int CDistance::add(const CDistance& total) const
{
	cout << feet + inches;
	return 0;
}

int CDistance::subtract(const CDistance& total) const
{
	cout << feet - inches;
	return 0;
}


int main()
{
	char choice;
	CDistance d1(0, 0);

	d1.setDist();
	d1.printDist();
	d1.add();
	_getch();
	return 0;
}

You declared member function add as having one parameter but you are trying to call it without any argument. So the compiler issues an error because the number of arguments does not correspond to the number of parameters.

how would I fix this?

The number of arguments shall correspond to the number of parameters. Is it clear?
