Linear search: Linear search or sequential search is the process of searching for a particular element that is present in the array one by one till the last element in the search element is found. The search uses a loop that iterates from the beginning till the last element to find the search element. The search continues for all the elements present in the array until the last element. The search of the target element is made after comparing it with each and every element that is present in the array. The search process continues until the target value or search value is found. If the search element is not found, the search gets returned unsuccessfully.

A3Q3.c - You are to write a C program that implements the following disk scheduling algorithms: a. FCFS [10 marks] b. SCAN [10 marks] c. C-SCAN [10 marks] d. SSTF [10 marks] e. LOOK [10 marks] f. C-LOOK [10 marks] • Your program will service a disk with 300 cylinders numbered 0 to 299. • • • • The program will service the requests (a list of 20 cylinder numbers) given in the file request.bin. This file contains (4 byte) integer values representing requests ranging from 0-299. Your program will take the initial position of the disk head as the first command line argument and the direction of the head as the second command line argument. It will then output the requests in the order in which they are serviced, and the total amount of head movements required by each algorithm. In particular, your program needs to do the following: Your program should take two command line arguments a) First command line argument - initial position of the disk head (an integer value) b) Second command line…
