C. Lab Overview – Scenario / Summary:
TCO #4
–
Given a simple business problem that requires one or more decisions,
create a solution algorithm that uses decisions with logical and
relational expressions.
TCO #5
–
Given a simple business program that requires iteration, create a
solution algorithm that employs loops.
TCO #9
–
Given a program with logic errors that is intended as a solution to a
simple business problem, employ debugging diagnostics to remove
and correct the errors.
Scenario:
Your algorithm will keep track of a customer’s purchases at the local
fireworks stand. Customers will not know exactly how many items
they will purchase, so using a FOR loop on this lab is not allowed.
Let’s keep the rules simple.
1) Accept the dollar value of each item purchased from the user until
the user is finished.
2) When purchases are complete, enter a sentinel value of -1
(indicating the user has finished).
3) If more the item purchased is 50.00 or more, give your customer a
10% discount on their item purchased.
4) Display all of the purchases to the customer with the original price
and the discount price.
Be sure to THINK about the logic and design first (IPO chart and
pseudocode), then code the Visual Logic command line processing.

Given a simple business problem, design a solution algorithm that
uses arithmetic expressions and built-in functions.
Assignment:
Your goal is to solve the following simple programming exercise.
You have been contracted by a local restaurant to design an algorithm
determining the total meal charges. The algorithm should ask the user
for the total food purchase and the tip percent. Then, the algorithm
will calculate the amount of a tip, a 7% sales tax, and the total meal
charge (including tip). The food purchase, sales tax, tip amount, and
total meal charge will need to be displayed to the customer.
Display all output using currency formatting (built-in Visual Logic
function).

Advanced (optional): use a constants for the 7% sales tax.

Week 3 Activity – Calculate Overtime Pay TCO #4 – Given a simple
business problem that requires one or more decisions, create a
solution algorithm that uses decisions with logical and relational
expressions. TCO #9 – Given a program with logic errors that is
intended as a solution to a simple business problem, employ
debugging diagnostics to remove and correct the errors. Assignment:
You will need to design an application that it will prompt a user for
their hourly pay rate, their hours worked, and whether they are single,
married, divorced, or widowed. It will then calculate their gross and
net pay. If they work more than 40 hours, overtime is calculated at 1
½ times the regular rate and displayed separately. If they are married,
use a flat tax rate of 15%. If they are single, use 22%, if they are
divorced, use 23%, and if they are widowed, use 13% (I realize that
these are not very realistic). Here is a sample of what the program
should do when run: (No overtime example) Enter hourly pay rate:

10.00 Enter hours worked: 35 Enter letter for (M)arried, (S)ingle,

CIS 115 Week 4 Lab Grade Calendar
You have been asked to design a program that will allow a teacher to
calculate the percentage and the final grade for students in a class.
The program will prompt the teacher to enter the student’s first and
last name and the number of points the student received. The program
shall only accept scores between 0 and 1,000 points (including 0 and
1,000), with 1,000 points being the maximum number of points. If the
input value is within the valid range, the program will display a "good
score" message; otherwise, the program will display an error message
and then terminate the program. The program shall then calculate the
score percentage, and then determine the grade based on the
percentage using the following grade criteria:
Score Percent Range
Grade
90-100
A
80-89
B
70-79
C
60-69
D

The program will then display the student’s first name, last name,
number of points, calculated percentage, and the final grade.
The program shall have an initial prompt informing the user of the
program's purpose, and a program termination message.

Assignment: Arrays are incredible fun! Today we are going to work
on a program to keep track of our homework scores for a math class.
Write a program that accepts five homework scores as input values
and stores them into a table (which is another name for an array).
Once the scores are in the array, we can process them again and again.
First, load the scores in your array. Second, display the contents of the
array in order. Third, display array in reverse order. Fourth, calculate
the average of the five scores entered in the array. Finally, the
algorithm should display all the homework scores in the array that are
larger than the previously calculated average. Make sure you use
some output statements to clarify all the details you are displaying,
being cautious about spelling and communicating to your user.

Assignment: Your goal is to solve the following simple programming
exercise. You have been asked by your accounting department to
design an algorithm determining the annual profit for your company.
The algorithm should ask the user for the projected monthly sales for
12 months. Then, you need to determine the annual profit and display
it to the user. The annual profit is 21% of the total sales.
Part A: Using Visual Logic, write the monthly sales amounts to a file,
monthly_Sales.dat. (Hint: be sure to enter a sentinel value for end of
file processing later.)
Part B: Using a separate algorithm, use the monthly_Sales.dat file as

In this lab, you are going to extend the Fireworks Checkout Stand
application in Week 6. This week, we will be more efficient by using
files and modularizing the program. This week, we will also load our

array of valid zip codes from a text file. In addition, we will modify
the existing code to create a modularized design.
Load the array via a .txt file. Prompt to see if the user wants to search
for a zip code. Prompt the user to enter a zip code and search against
the array. If the zip code is found in the array, continue processing the
sale. If the zip code is not found in the array, display a message
stating, "State law prohibits selling fireworks for people living in the
zip code". Modularize your code.
