Question

CODE IN C++

Write a program that simulates a microprocessor with eight pins Each pin is of enumerated type and serves a device from the set ground, power, usb, available, camera, audio, keyboard, monitor When a signal is set on a pin, it serves the connected devices by turning it on. Simulate real life pin interrupts in an operating system using a random number generator and a forever loop Your output must look like this: ervicing KEYBOARD ervicing AUDIO amera On ervicing CAMERA ower On amera On ervicing CAMERA round On udio On ervicing AUDIO SB On ervicing USB Monitor On ervic amera On erv SB On ervicing USB udio On ervicing AUDIO ing MONITOR icing CAMERA

//method to simulate the pin interrupts

                //defining an object of Type enum

                Type pin;
