Question No: 06This is a subjective question, hence you have to write your answer in the Text-Field given below.Consider P0,P1,P2 are three processes synchronised with semaphores S0=1,S1=0,S2=0 as showninitialised. The table below gives the code of the processesProcess POWhile (true) {Process PIProcess P2Wait(S2);print 1";signal(S1),wait(S1);signal(S1);wait(so);print *0";signal (S1);signal (S2);a If the sequence of processes schedule is P1,P2,P0,P0,P2,P0,P2,P0. What are thevalues printed?b. If the semaphores are initialised with S0-0,S1=1 ,S2=1. What are the values printedfor the above sequence?

0 1 process P1 executes first, as S1=0 it would not execute similarly P2 now P0 executes and prints…

You are working for a software firm, and you have just completed a program containing about 1 million lines of code. The program makes computational predictions for a complex systems-akin to a more sophisticated version of the pre-lecture activity simulations which you have run in class. However, when you run the program to check your answer, you get a wrong output answer (the software generates too many predictions). You are not sure wherein the error lies, and thus you must search through the entire million lines of code to verify that each line is correct. How much time will this take? Assume that there are no computer crashes while you search. This should take you about S
Write a C program to create two processes P1 and P2. P1 takes 2 integers (x,y) and passes it to P2. P2 performs mathematical operations over receivedintegers and sends it back the output array to P1 for printing.

SYSTEMS PROGRAMMING:
This needs to be done in C Programming. A manufacturing plant has an alarm monitor program that reports any of sixteen possible alarms. A 16-bit variable ALARM is examined, and each 1 bit found corresponds to an active alarm. The alarms are numbered 1 – 16, with the least significant bit (LSB) corresponding to Alarm 1 and the most significant bit (MSB) corresponding to Alarm 16. Prompt for the unsigned short integer ALARM, and then use bitwise logic to determine and display all corresponding active alarms, e.g., output “Alarm 12 Active”.
