Description:
You are to simulate the execution of interactive processes by a computer system with a large memory, one terminal per user, a CPU, and a disk unit. Each process will be described by its start time followed by a sequence of resource requests. It must be written in C or C++.

These resources requests will include:

a) CPU requests (CPU),
b) disk reads (DISK ) and
c) terminal accesses (TERMINAL).

Your input will be a sequence of pairs as in:
QUANTUM 100
START 12000
CPU 100
TERMINAL 5000
CPU 100
DISK 10
CPU 20
TERMINAL 2000
START 12000
CPU 30
...
All times will be expressed in milliseconds
When a process exceeds its CPU quantum, the OS will move that process to the end of the ready queue and allocate the CPU to the first process in line (head of the ready queue).

To simplify your life, we will assume that:

a)there is enough memory space for all processes,
b)context switch times can be neglected,
c)user think times are included in the terminal access
times, and
d)each process reads and writes to a different terminal.

When all the processes in your input stream have completed, your simulator should print a summary report listing:

a)the CPU quantum,
b)the number of processes that have completed,
c)the total number of disk accesses,
d)the average duration of a disk access (including the
waiting time in the disk queue),
e)the total time elapsed since the start of the first
process,
f)the maximum lengths of the CPU and disk queues,
g)the CPU and disk utilizations, that is, the fraction
of time the CPU was busy.

Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
