Explanation Class Definitions: Multiplexer: Simulates the multiplexing of data from multiple input queues into a single output queue. Private Members: inputQueues: A vector of queues where data is added for multiplexing. outputQueue: A single queue where data from all input queues is combined. Public Methods: addData(int inputIndex, int data): Adds data to a specific …
