Hi,<BR><BR>I have a base class whose destructor is pure virtual, so the class is abstract.<BR><BR>I have a derived class (subtype) whose multi-argument constructor wants to call the base class's ...

This demonstrates how to create a pure virtual class (interface) in C++ and how to derive concrete implementations from it. This example builds a hypothetical system to insert or remove users in some ...

This derived class extends the RFM69 library by providing a mechanism for automatic transmit power control. On startup you tell the RFM69_ATC object a target RSSI value (your signal strength at the ...

Is there a clever way to hide (what would be public) base class functionality from derived classes? My first thought is to simply redirct the function call to a private function, but this would ...
