The purpose of this programming assignment is to develop a file editor that supports

both text as well as binary mode.

You are already familiar with text editors, for example, while working with Linux OS

you might have used vi, a full screen text editor or ex a line text editor. (If you do not

know this then it is time you learn about it!) You would have noticed that neither of

these text editors can be used effectively to edit non-text files, such as executable

files, directory files or data files used for databases (try yourself). These files are not

line oriented; they are not made up of lines of characters separated by newline

characters. The binary file editing mode you will develop will be useful in studying

and modifying such binary files. …show more content…
Your program should be

compiled as myEdit and accept command line arguments. Following shall be the

commands to execute the program. Argument --B or –Binary shall are optional

and if used, it indicates that file need to be treated as binary.

myEdit [--B]

myEdit [--Binary]

Write a ‘C’ program on Linux to take a file name as command line argument and

provide an interactive interface to edit a file. The specified file is to be viewed as a

stream of bytes. Since there is no concept of line in a non-text file, assume that each

“line” is to be 40 bytes (each character requires one byte in a text file. So a line

should be able to display 40 characters). Only last line of the file can be less than 40

bytes. You shall also be using a cursor to denote the position of the current character

under consideration. Editor should display

1. header showing name of file,

2. a content window (size 10 lines, 40 characters each) showing address (offset

as a hex number within file) followed by the 40 characters of the line

3. a status showing row and column of the cursor.
