In this assignment you will write a system utility that displays the space utilized by les within the current working directory. Each le and directory will be displayed, prexed by the space it takes up. Space will be displayed in a user-friendly format (e.g., B, K, MB). The utility will be recursive in that it lists the space used by les nested within a child directory in the current directory. Your program must compile and run under Xubuntu (or another variant of Ubuntu) 16.04. Sample output:

Specic Requirements: 1 The size of each directory should be calculated recursively. Calculations must include the size of folders themselves (4096 bytes). [8 points]

The list of entries should be alphabetized and case insensitive. (Implement a sorting algorithm.) [7 points]

Show the size of each entry in a user-friendly format: if it is less than 1024 bytes, show B for bytes. If it is less than 10242bytes, show K for kilobytes. Otherwise, show MB for megabytes. [5 points] When the command is executed at a directory, each le and directory within it is displayed. In addition, the contents of child directories is shown. [10 points]

Must show a . directory which is the size of everything in the current directory and all children (recursive). [5 points]
