File System: It is highly useful in file system handling where for example the file allocation table contains a sequential list of locations where the files is split up and stored on a disk. Remember that overtime it is hard for an OS to find disk space to cover the entire file so it usually splits these up into chunks across the physical hard drive and stores a sequential list of links together as a linked list. Write an algorithm for the above problem and analyse the efficiency of the algorithm.

C++ You must create a header file for each task with implementation as the execute task. Input file A contains numeric values  and the Output File A is sorted.  Algorithm:  a ← read Value from file (A);  while not End Of File (A) {       b ← read Value from file (A);       If a> b {             return false;        }       a ← b;    } return true;

createDatabaseOfProfiles(String filename) This method creates and populates the database array with the profiles from the input file (profile.txt) filename parameter. Each profile includes a persons' name and two DNA sequences. 1. Reads the number of profiles from the input file AND create the database array to hold that number profiles. 2. Reads the profiles from the input file. 3. For each person in the file 1. creates a Profile object with the information from file (see input file format below). 2. insert the newly created profile into the next position in the database array (instance variable).

Local addresses The "A1" address system has coordinates that exist over the whole worksheet. If you have a block of data specified somewhere within that worksheet, it can be useful to be able to specify the addresses relative to that block. This can be done with INDEX(), which takes 3 arguments. The first argument is a rectangular range of data, for example A2:E8. The second and third arguments are numbers specifying an offset down then right from the top left of that data range. Unlike OFFSET(), the numbering starts at 1, so INDEX(A2:E8, 4, 2) refers to cell B5. Instructions Use the block of data for North East India + North Myanmar, from A11 to G19 as the reference. In cell I1, use INDEX() to get the number of Blues in Sikkim. In cell I2, get the number of White-yellows in Mizoram Hills. please show the formulas in excel thank you :)    Area Locality Skipper Swallowtail White-yellow Blue Brush-footed Blues in Sikkim   Indian Subcontinent Indian Subcontinent 307 94 99…

File Attributes 5. File attributes (a) File name: file name is a very important file attribute When a file changes name, it seems to change its identity (just like when you change your name) The oldest file naming we may remember is the 8 +3 convention in DOS (in DOS, all file names can NOT be bigger than 8 characters, special characters like spaces were not allowed etc.). So a file like C:\\Program Files\\Adobe\\Photoshop can cause problems in DOS, and it has to be represented in different ways using strange character like~ (tilde). Elaborate on your understanding of file names or file naming in different operating systems (Windows, Mac, Linux etc.). For example, some OS like NTFS may allow longer file name, allow space, and even allow non English like characters such as Chinese file names. Is there a maximum length of file names (can you have a file name of 1,000 characters long?) (b) File creation date and modification date. File can be created and modified using different ways of…

in C# Code in VS studio: Create a program that has 2 options for a user to select. The first option accepts information from the user and then save that data to a file on disk. The second option loads all data stored on that file.

C# Write, compile, and test a console application named FileComparison that compares two files.  First, use a text editor such as Notepad to save your favorite movie quote.  Next, copy the file contents, and paste them into a word-processing program such as Word.  Then, write the file-comparison application that displays the sizes of the two files as well as the ratio of their sizes to each other.  To discover a file's size, you can create a System.IO.FileInfo object using statements such as the following, where FILE_NAME is a string that contains the name of the file, and size has been declared as an integer: FileInfo fileInfo = new FileInfo(FILE_NAME) ;Size = fileInfo.Length;

C# please  Write a program that will create file with at least 10 lines. Each line of your file should have information delimited by some delimiter (I.e., commas, spaces, slashes, symbols, etc.). After your file has been created with the proper amount of data, you should read your file line by line and display without the delimiters in the same program after closing your writer. Additionally, the information stored into your file should be data that is gathered from a separate class.   Your program should save your file in a specific directory. To promote flexibility, your program should check to see if the chosen directory exists prior creating it, and if it does not exist, your program should create it for you. Additionally, you should allow the user to enter the names of the directory and file instead of hard-coding it into your program.

JAVA PPROGRAM   Write a program that prompts the user to enter a file name, then opens the file in text mode and reads names. The file contains one name on each line. The program then compares each name with the name that is at the end of the file in a symmetrical position. For example if the file contains 10 names, the name #1 is compared with name #10, name #2 is compared with name #9, and so on. If you find matches you should print the name and the line numbers where the match was found. While entering the file name, the program should allow the user to type quit to exit the program. If the file with a given name does not exist, then display a message and allow the user to re-enter the file name. The file may contain up to 100 names. You can use an array or ArrayList object of your choosing, however you can only have one array or ArrayList. Input validation: a) If the file does not exist, then you should display a message "File 'somefile.txt' is not found." and allow the…
