I’m using a library that features callbacks extensively. Unfortunately, many of the methods accept callbacks in two or more formats. This was done as a convenience, but a side-effect is that it prevents the use of polymorphic lambdas (lambdas with parameters declared as auto). Example: namespace Library { struct Gear final {}; struct Bolt final ..

Three nodes Node1, Node2 and Node3 are connected in point to point fashion as – Node1–>Node2–>Node3. Node1 is the source node and generates packets at the rate of 50 packets/sec. Node2 simply forwards the packets to Node3 which is the destination node. And Node3 deletes all the packets, and for every tenth packet received by ..

I recently picked up programming again since I remembered it being a "fun" hobby a long time ago. Problem is that I have to relearn even the most basic things.
