Error in Operator Overloading

[DutchDude]

This program is supposed to receive numbers (hours minutes seconds) that will add an object time. But when compiling the compiler tells me: error: `Time Time:: operator + (long int, long int, long int) 'must take either zero or one argument.
The error is at line 9 of time.hpp.

# define time
 
 time class 
  ( 
      public: 

      Duration (a_hours int = 0, int a_minutes = 0, int a_seconds = 0); 
      Time operator + (long hours, long minutes, long seconds); 
      Time operator + (const Time & duration); 
      void display (); 

      private: 

      int m_hours; 
      int m_minutes; 
      int m_seconds; 
  ); 

  # endif

First mention of integer in the error message that is long shortcut to long integer. it is what is marked in the message (long int).

  Time operator + (long hours, long minutes, long seconds);

Then, the error message is quite clear there should be one or zero arguments to overload the + operator.
I think you wanted to do:

  time1 = time2 + hours + minutes + seconds

Translation of the error:
Service Time Time:: operator + (long int, long int, long int) should take one or no argument.In other words you can not overload a operator giving more than one parameter, it does not make sense elsewhere. And this is not overloaded. When you want to add directly with just 3 values that you call the constructor like this time (N1, N2, N3), and your second operator + will be called.
