Purpose: Write a program to implement deterministic evaluation of CPU scheduling algorithms

with the average waiting time criterion.

Scheduler Sanpshot: Initial ready queue has $5$ processes where each process has the following

attributes:

i$)$ an identifier $($value between $0$ and $10,$ randomly assigned $-$ however, no two processes

can have the same id$)$

ii$)$ a burst length between $20-100,$ randomly assigned when the process is created

iii$)$ a priority between $1$ and $10($low value indicates higher priority$),$ randomly assigned

when the process is created $($two or more processes may have same priority rank$).$

Requirement $1$: Display initial snapshot of the system with the information of above $5$ processes as

following tabular manner $($order the entries in increasing ID number$)$:

Process ID

Priority

Burst$-$length

RUBRIC: Correct values within the range $($ID$,$ burst length, priority$)[3]$

Non$-$duplicate ID

$[1]$

Display of the initial snapshot $($correct tabular format$)$

Requirement $2$: Now, allow user of the program to enter attributes $($id$,$ priority, and burst length$)$ of

another process $($the $6^{th}$ one$).$ Make sure the following are satisfied:

i$)$ user may enter any integer as a process ID$.$ Your program must check the appropriate

range $(0$ to $10).$ Also, user entered value should not be a duplicate of already created IDs.

Any of these violated, user must be notified and given chances to enter a valid ID$.$

ii$)$ User may enter any integer as burst length. Your program must check the appropriate

range $(20$ to $100).$ If violated, user gets chances until an acceptable value is entered.

iii$)$ User may enter any integer as a priority value. Your program must check the appropriate

range $(1$ to $10).$ If violated, user gets chances until an acceptable value is entered.

Display updated snapshot of the system $($with $6$ processes now$)$ in the same format as above

$($Requirement $1).$

RUBRIC: Correct input acceptance implementation
