file formatter

 source: Tino Duong, 2003

Description:

You have just written a user manual using xemacs file editor. After reading it over, you noticed that the file is in desperate need of formatting. Your job is to write a file formatter that takes text in a text document and formats it nicely into a new document where the lines are the same size. The program must read a file and output a new file under the name format.txt.

Requirements:

• The program must read in the input file name from the command line.

        The usage should like similar to this format
                ./a.out <input file>

                -Where a.out is the executable
                -<input file> is the name of the file   

• If the user enters an invalid file name , the program should display an error message and abort
• If the user passes incorrect information via the command line (e.g. improper usage) the program should display an error message and abort
• The program must print the newly formatted document to a file called "format.txt"
• The program must format the file into a document with the lines 80 characters long.

Additional Requirements:

• Have the program prompt the user for the line size they wish to format the document in

Concepts:

• File Input/Output
• Algorithms
• Standard Input/Output
