## CIS115 Week 2 Exercise

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.
Be sure to THINK about the logic and design first (IPO chart and pseudocode), then code the Visual Logic command line processing. 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, (D)ivorced, (W)idowed: M Gross pay is \$350.00 Net pay is \$297.50 (Overtime example) Enter hourly pay rate: 10.00 Enter hours worked: 45 Enter letter for (M)arried, (S)ingle, (D)ivorced, (W)idowed: S Regular pay is \$400.00 Overtime pay is \$75.00 Gross pay is \$475.00 Net pay is \$370.50 Rubric: When completed staple the following documents together neatly in 1,2,3,4 order: 1) This instruction sheet first 2) The IPO Chart, second 3) The Pseudocode, third 4) The Flowchart and output example last.

## CIS115 Week 6 Exercise

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.

## CIS115 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.

Keep a tally of the number of items purchased. If more than 20 items were purchased, give your customer a 10% discount on the total purchases. Once purchases are complete, display the total number of items purchased, the average price of the items, the total of all fireworks purchased, any discount if applicable, and the total of all fireworks purchased minus the discount.

## CIS115 Week 7 Lab Fireworks Stand Checkout

n 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.
Be sure to THINK about the logic and design first (IPO chart and/or pseudocode), then code the Visual Logic command line processing.

The program will prompt the user to provide each employee’s full name, hourly pay rate, and hours worked. The program will then ask whether the employee is single or married. If an employee is married, the tax rate is 25%; if he or she is single, the tax rate is 20%. Also, if the employee worked more than 40 hours in a week, the number of hours greater than 40 is paid a rate 1.5 times the pay rate.
After all data are input and calculated, the program will display a payroll report with a list of all the employee names and weekly pay. In addition, the program will display the total payroll for the week and the average weekly pay.
Write a program using Visual Basic, prompt the user for the appropriate input, and display the output as described above. You may assume all data are valid. Provide a program introduction message that tells the user how to use the program
