Question
Purpose-This lab investigates an all too common occurrence: the bug in someone else’s C++ program.
Procedure
The program to be investigated during this lab procedure is provided for you in the Lab 14 assignment on WyoCourses. Your task is to debug the provided program and insert your modifications to correct its functionality.
The Setting: You’ve just started an internship with the IT department on the graveyard shift at the local medical center (eerie feeling, I know). The medical records team is in the midst of generating bedside applications for reducing the amount of repetitive handwriting required of nurses and technicians (and you thought those doctors couldn’t write because they were just spastic). The first application is supposed to generate a set of labels containing nurse, patient and simple vital sign information (to be stuck onto all of the various places that it needs to be recorded). The programmer assigned to the task has called in sick for the week (works in a hospital, go figure), so you are left with a buggy program. Here is how it works, in dialog form...
This is an okay run, but .... the name information on the label is not correct:
Enter nurse’s name: Betty
Enter patient’s name: Joe
Enter pulse rate: 60
Enter systolic BP: 120
Enter diastolic BP: 66
****************************************
Patient: Betty
Nurse: Joe* Pulse: 60
BP: 120/66
****************************************
When the input data for the names are expanded (full names), it really goes bad:
Enter nurse’s name: Josephine Nightingale
Enter patient’s name: Enter pulse rate: 82
Enter systolic BP: 140
Enter diastolic BP: 96
****************************************
Patient: Josephine
Nurse: Nightingale
Pulse: 82
BP: 140/96
****************************************
And here is an example dialog of the desired behavior:
Enter nurse’s name: Josephina Wilhemina Frankenheimerstein III
Enter patient’s name: Poor Unfortunate Soule
Enter pulse rate: 72
Enter systolic BP: 124
Enter diastolic BP: 80
****************************************
Patient: Poor Unfortunate Soule
Nurse: Josephina Wilhemina Frankenheimerstein III
Pulse: 72
BP: 124/80
****************************************
Your only communication with the original programmer consisted of a phone call (subdued sounds of ocean surf and seagulls in the background) and a text message, both involving hints toward “I’ve never really gotten used to this C++ thing, C worked so well,” and “I should have used string::getline() or something like that”, oh, and “don’t forget about buffer overflow!”
1.Build a new project and insert the “problem code.”
2.The files are all available on the WyoCourses assignment. Lab14.cpp, Lab14Funcs.cpp, Lab14Funcs.h
3.Build and run the program with debugging enabled. That way you might see what is going on, especially if you step through the program.
4.Make your edits to the Lab14 files as necessary. This will likely involve some use of the iostream getline() method and the string::getline() function.
You might search the Web (cplusplus.com for example) for documentation and examples of the use of these.
You might also consider validating the user’s input. For instance, the values used for a BP or a pulse are always integers.
You cannot limit the length of the nurse’s name or patient’s name. You need to handle relatively large/long names. For instance, deciding that the name should only be 50 characters would be too small.
Test your solution to ensure that the example desired behavior is achieved.
Make sure that YOUR NAME appears in all the files’ comment headers.
Upload your solution as four (4) files to the Lab 14 assignment.
The source code of your solution: Lab14.cpp, Lab14Funcs.cpp and Lab14Funcs.h
An annotated text file containing demonstration of your program’s behavior:
Lab14Test.txt.
