C++ or Java Implementation of a Simple File System in OS

Use C++ or Java to implement a File System. Implement functions below and follow the specifications: The following commands will be used in the test files for this project: ● cr <name> o create a new file with the name <name> o Output: <name> created ● de <name> o destroy the named file <name> o Output: <name> destroyed ● op <name> o open the named file <name> for reading and writing; display an index value o Output: <name> opened <index> ● cl <index> o close the specified file <index> o Output: <index> closed ● rd <index> <count> o sequentially read <count> number of characters from the specified file <index> and display them on the terminal o Output: <xx...x> ● wr <index> <char> <count> o sequentially write <count> number of <char>s into the specified file <index> at its current position o Output: <count> bytes written ● sk <index> <pos> o seek: set the current position of the specified file <index> to <pos> o Output: position is <pos> ● dr o directory: list the names of all files o Output: <file0> <file1> ... <fileN> ● in <[login to view URL]> o create a disk using the prescribed dimension parameters and initialize it; also open directory o If file does not exist, output: disk initialized o If file does exist, output: disk restored ● sv <[login to view URL]> o close all files and save the contents of the disk in the specified file o Output: disk saved ● If any command fails, output: error Disk and File System Specification: ldisk: 64 blocks block = 64B = 16 integers block 0 holds bitmap: 64 bits (one per block) = 2 integers descriptor: 4 integers file length (1 int) 3 block #s # of descriptors: 24 = 6 blocks descriptor 0 describes the directory each directory entry: 2 integers file name: maximum 4 chars, no extension (1 int) descriptor index: 1 integer ldisk can be saved into a text file at any point with the sv command ldisk can be restored from a previously saved text file ising the in command a new empty ldisk is created if no saved file is given directory is opened automatically with in command (OFT index = 0) OFT has 4 entries: directory plus up to 3 other open files all files (including directory) must close with sv command Read input and output from a file Sample input and output INPUT: in cr foo op foo wr 1 x 60 wr 1 y 10 sk 1 55 rd 1 10 dr sv [login to view URL] in [login to view URL] op foo rd 1 3 cr foo cl 1 dr OUTPUT: disk initialized foo created foo opened 1 60 bytes written 10 bytes written position is 55 xxxxxyyyyy foo disk saved disk restored foo opened 1 xxx error 1 closed foo More Info to be found in the attached files
