The Observer Pattern avoids direct object interactions and can be used when one or more objects are interested in the state changes of a given object.The Observer Pattern can help to maintain the state consistencies between objects, and enhance the correctness and the quality of the system.

The observer management, however, is not becoming less complex. But as @R. Martinho Fernandes mentions: an std::vectorc++ How to use signals and slots for observer pattern? -… So, in terms of signals and slots. The basics are that you connect signals to slots, which will be called each time the signal they're connected to is emitted. To go further, you could for example have a slot in the Observable, connected to a signal that an Observer will emit to tell the Observable it has to be...

My own signal-n-slot definition The KjellKod signal-slot mechanism is a C++, cross platform compatible implementation of the Observer design pattern .A signal can be connected to many slots and all slots/receivers are notified when the signal is emitted.

Signals & Slots | Qt Core 5.12.3 Signals and slots are loosely coupled: A class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type.
