# -------------- PROBLEM ----------------------

# Chapter 11, Programming Exercise #11
# Write an automated censor program that reads in the text from a file and creates a new file where all of the four-letter words have been replaced by "****". You can ignore punctuation, and you may assume that no words in the file are split across multiple lines. (Note from Mr. White: This exercise is being modified so that the program accepts input from the user, not from a file.)






















































# -------------- PSEUDO CODE -------------------

# Define the function censor()

#    while the user enters lines:
#        Get a line of input from the user
#        Look for a curse word, if found
#        Replace the curse word with ****
#        Print out the new line.

# Call the function censor()
