Question 4. Creating xv6 file system mapping utility Write a program using Ubuntu's defauilt gcc compiler that reads fs.img file produced by xv6 make process and prints out its map as a string of text, in which every character corresponds to a single data block. The first character corresponds to block 0, second character corresponds to block 1, and so on. The glyph used for each character represents its type: ● 'B' - boot block 'S' - superblock 'L' - block that contains part of the file system log 'I' - block that contains part the file system i-node table 'T' - block that contains part of the file system bitmap 'D' - a data block Please refer to the following picture, xv6 book, and xv6 mkfs/mkfs.c and kernel/fs.c source code for more detail: 0 boot super 1 2 log inodes bit map data data

Game of Hunt in C++ language Create the 'Game of Hunt'. The computer ‘hides’ the treasure at a random location in a 10x10 matrix. The user guesses the location by entering a row and column values. The game ends when the user locates the treasure or the treasure value is less than or equal to zero. Guesses in the wrong location will provide clues such as a compass direction or number of squares horizontally or vertically to the treasure. Using the random number generator, display one of the following in the board where the player made their guess: U# Treasure is up ‘#’ on the vertical axis (where # represents an integer number). D# Treasure is down ‘#’ on the vertical axis (where # represents an integer number) || Treasure is in this row, not up or down from the guess location. -> Treasure is to the right. <- Treasure is to the left. -- Treasure is in the same column, not left or right. +$ Adds $50 to treasure and no $50 turn loss. -$ Subtracts…

9.Code please. In this exercise you will create a program that will be used in a digital library to format and sort journal entries based on the authors last name. Each entry has room to store only the last name of the author. Begin by removing the first name "Isaac" from the string variable journal_entry_1 by using the string function erase. Do not forget to also remove the whitespace so that the string variable journal_entry_1 will then contain the string "Newton" with no whitespaces. The journal entries should be sorted alphabetically based on the authors last name. For example, the last name "Brown" should come before the last name "Davis" Create an if statement so that if the last name contained within journal_entry_2 is alphabetically less than the last name contained within journal_entry_1, then the string values are swapped using the string function swap. You may use either of the comparison operators < > in the if statement but remember that following ASCII, "A" is…
