Suppose that the head of a disk drive is currently at track 9, that the disk has 32 tracks per surface, and the disk-queue contains the following sequence of access requests: Request 1 2 3 4 5 6 7 8 Track 18 22 14 26 10 30 75 For each of the following disk scheduling algorithms, find the total distance (in tracks) that the disk head moves. Please make your answer boldface.

In this lab, you add a loop and the statements that make up the loop body to a c++ program that is provided. when completed, the program should calculate two totals: the number of left-handed people and the number of right-handed people in your class. your loop should execute until the user enters the character x instead of l for left-handed or r for right-handed. the inputs for this program are as follows: r, r, r, l, l, l, r, l, r, r, l, x variables have been declared for you, and the input and output statements have been written.

Write code using c . (take input from user) calculate the size of a given file in kbs. in this task you will complete the function with the following prototype: float get_file_size(char * filename); the function takes the file name (address to the start of a null terminated character array) as input. the function should then open the file and find the number of bytes it contains till eof. the number of bytes divided by 1024 will give the size in kbs. if the file cannot be opened the function should return -1.
