CMIS 325 – Final Project
The ‘official’ requirements for the final project, as presented in the course Syllabus/Project Descriptions are reproduced
Create and manage a phone book text data file.
Create five correctly working programs:
Each of these programs should work together as a unique application
Include documentation as header comment blocks for each program.
Your final project will be graded based on:
functionality (50 percent)
proper style: indentation, use of white space, variable names (10 percent)
adherence to requirements (30 percent)
user-friendly application (10 percent)
Please be aware that grading will be done according to the scheme included above and do not forget to include
documentation as required.
From Assignment 7 you already have the structure for the final project, thus the task for this week is to add two new
functions, for changing an entry in the phone book, and for removing an entry. Updates are required in the main part of
the script to include the two new options in the menu, and there is also a supplementary requirement for the Add
function: now you have to check that the phone number is typed in the format ddd-ddd-dddd (Please do not forget to
make this change! There is a post in the Assignment 7 conference about how to proceed for this test.)
More detailed requirements for the two new functions are presented next. In both functions the phone book file must be
searched for a certain line, and that line, if found, is either modified, or deleted. The search will use as ‘key’ the last
name and first name of a person. In case there is no such line in the phone book, both functions should return with a
message informing the user that the key is not present in the file. To simplify the requirements, assume that there is at
most one entry in the phone book for a given person.
This function requires from the user the Last Name and First Name of a person and searches the phone book for a
corresponding entry. If no such entry is found, the function displays a message informing the user; if the entry is found,
that line must be removed from the file, and then the function informs the user about the success of the operation. The
function requires an acknowledgement from the user (type any character) to return to menu display.
This function must change the phone number of a specified person (Last Name First Name.) It asks the user to type Last
Name, First Name and New Phone Number. If there is no entry for the specified person, the function displays a message
informing the user; if the entry is found, that line is replaced with a line containing the name of the person and the new
phone number; then the function informs the user about the success of the operation. The function requires an
acknowledgement from the user (type any character) to return to menu display.
1. This time the functions can have the simple names: add, display, change, remove.
2. Think of using commands that were also used in previous assignments for processing text files.
