- Create a program 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 files size, you can create a System. 10. Filelnfo 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;When you work with a __________ file you access data from the beginning of the file to the end of the file. a. direct access b. random access c. sequential access d. binary accessThe term __________ is used to describe a file that data is written to. a. input file b. output file c. saved file d. user file
- Fill-in-the-Blank The __________ function reads a line of text from a file.When a program works with an input file, a special value known as a(n) __________ is internally maintained for that file and marks the location of the next item that will be read from the file. a. input locator b. accumulator c. read position d. sequential read valueThe term __________ file is used to describe a file that data is read from. a. data b. write c. read d. input
- Please in C Language Write a program that uses an existing text file (text.txt) to determine the number of occurrences of each letter.
