Adding the value a pointer points to to an object array

otisphat80 (37)
Hello everyone I am having a hard time with this. I have been at this since 5:00 this morning. I am working on the command pattern for design patterns class. My book is in Java so i am translating the book examples to c++. in this code I am trying to assign the object that two pointers point to to an object array. Gcc keeps pointing to the assignment operator in the remote control constructor .Here is the error I get:

/home/Copy/C++_Projects/Design_Patterns/Command_Pattern_CL/remote_control.h:19:25: error: no match for 
‘operator=’ in ‘((RemoteControl*)this)->RemoteControl::m_on_commands[slot] 
= on_command’


There is a total of 21 classes in this program. So I tried to only post what I think is nessary please let me know if you need more I will post on paste bin. I cant even start on my actual assigment untill I get this working. Thanks .

You never overloaded the = operator for your command class, but use it in the constructor to the RemoteControl class.

Thanks for the reply I thought of that but how do I do that for an abstract class the command class has nothing in it but a virtual function.
