The first part of this project requires that you implement a class that will be used to simulate a disk drive. The disk drive will have numberofblocks many blocks where each block has blocksize many bytes. The interface for the class Sdisk should include : An explanation of the member functions follows : - Sdisk(diskname, numberofblocks, blocksize) This constructor incorporates the creation of the disk with the "formatting" of the device. It accepts the integer values numberofblocks, blocksize, a string diskname and creates a Sdisk (software-disk). The Sdisk is a file of characters which we will manipulate as a raw hard disk drive. The function will check if the file diskname exists. If the file exists, it is opened and treated as a Sdisk with numberofblocks many blocks of size blocksize. If the file does not exist, the function will create a file called diskname which contains numberofblocks* blocksize many characters. This file is logically divided up into numberofblocks many blocks where each block has blocksize many characters. The text file will have the following structure : - getblock(blocknumber,buffer) retrieves block blocknumber from the disk and stores the data in the string buffer. It returns an error code of 1 if successful and 0 otherwise. - putblock(blocknumber,buffer) writes the string buffer to block blocknumber. It returns an error code of 1 if successful and 0 otherwise. IMPLEMENTATION GUIDELINES : It is essential that your software satisfies the specifications. These will be the only functions (in your system) which physically access the
