Operator overloading,initization, Print() in header file

I'm currently writing a header file for a Car class. But The problem is I don't know how to initialized in the Car class and use the copy constructor in the header file. Also, this header file requires a operator function. When I compile it, I have a syntax errors for those two operator function. For the Print() method, I have to use it for display the mantfacturere, model, year, total manufacture, total kilometers travelled and the amount of fuel costs, total number of services and fuel economy with print method. Can anyone please take a look at my code and help me fixing some of the mistakes in the header file?

Thank you

PHP Code:


		
			
#ifndef CAR_H

#define CAR_H

#ifndef LEN

#define LEN 25



class Car

{    

       private:

           char name[LEN]; 

           char model[LEN]; 

           int year;

    

       public:

            Car();

            Car(char *m, char *n, int y);

            Car(const Car &source);              //copy constructor

            const Car operator +(const Journey& meter) const;

            const Car operator +(const FuelPurchase& amount) const;

            void print(void) const;        

            ~Car();

};

#endif

PHP Code:


		
			
const Car operator +(const Journey& meter) const;

const Car operator +(const FuelPurchase& amount) const;

Should be:

PHP Code:


		
			
const operator +(const Journey& meter) const;

const operator +(const FuelPurchase& amount) const;

Re: Re: Operator overloading,initization, Print() in header file

You're right, I am wrong.

I thought he was using the class name and forgetting the scope resolution operator ::, which is only needed in the definition outside of the class. I didn't look at it carefully enough. The only thing wrong with his code is the const at the start. His code should be:

Code:

Car operator +(const Journey& meter) const;
Car operator +(const FuelPurchase& amount) const;
