Homework 9 Feedback.

• Some notes
  • Do not use arrays, string streams, lists, maps, or any other item we have not discussed.
  • The problem can be solved with loops, if statements and strings.
  • The purpose of the problem is to learn to do functional decomposition and use functions.
    • Break the problem into smaller pieces.
    • If needed break those pieces down further
    • Write a function for the small pieces
• My design

  • main
    open the master file 
    get a file name
    while success
        process a file
        get a file name
    close the master file.
    
    process a file
    Input: the base file name
    
    construct the input and output file names
    open the input file
    open the output file
    if successful
        process the message
    else
        print an error message
    
    close the input file
    close the output file
    
    process the message
    Input: open input file, open output file
    
    get a line
    while successful
       decode the line
       write the word to the output file
       get a line
    
    
    decode a line
    Input: a line of text
    Output: a word
    
    Get the count and direction
    If the direction is left 
        reverse the line
        subtract 1 from the count
    Get the word at position count from the line
    return this word.
    
     get the word at position count
    Input: a line of text
           a count
    output a word
    
    set position to 0
    while position is less than count
         space = find the position of the first space
         word = everything before the first space
         line = everything after the first space
         increase position by 1
    return word
