Q.No.1:Suppose in a Hospital, there are two physicians to dealwith patients. Patients of all ages come for their checkup. Physician ‘A’ is designatedas physician of old patients while physician ‘B’ has to check other patients.Many patients come to the hospital at the same time. There are two queuesof patients against each physician. If patient is an old man, he will stand in secondqueue; otherwise he will stand in first queue. Both doctors check their patients one byone on first come first served basis. Due to timing restriction of the hospital, each doctorcan check a maximum of 20 patients per day. You are required to write a program in C++ to implement the above scenario. It shouldbe clear that patients will be added on back/rear side of the queue and will be servedfrom front of the queue. Further, your program should use Queue as an array toimplement above scenario.

The defenders agree to a pact to determine which of them is to go for help. The defenders form a queue and they pick a number from a hat. Beginning with the first officer in the queue, they begin to count. As each defender counts off, he moves to the end of the queue. When the count reaches the number that was picked, that defender is removed from the queue, and the count begins again with the next man. Once an defender is removed from the queue, he is no longer counted. The last defender that remains in the queue is the one that rides away on the horse to summon help. —————————— The countOff() method displays the name of each officer removed from the queue, in the order in which they…
