Lab 04: Control Statements and Jumps-2024.10.15

1. Write a program that requests the hours worked in a week and then prints the gross

pay, the taxes, and the net pay. Assume the following:

a. Basic pay rate = $10.00/hr

b. Overtime (in excess of 40 hours) = time and a half

c. Tax rate: #15% of the first $300, 20% of the next $150, 25% of the rest

Use #define constants, and don’t worry if the example does not conform to current

tax law.

2. Modify assumption a. in exercise 1 so that the program presents a menu of pay rates

from which to choose. Use a switch to select the pay rate. The beginning of a run should

look something like this:

Enter the number corresponding to the desired pay rate or action:

1) $8.75/hr 2) $9.33/hr 3) $10.00/hr 4) $11.20/hr 5) quit

The program should request the hours worked if choices 1 through 4 are selected. The

program should recycle until 5 is entered. If something other than choices 1 through 5

is entered, the program should remind the user what the proper options are and then

recycle. Use #define constants for the various earning rates and tax rates.

3. Write a program that accepts a positive integer as input and then displays all the

prime numbers smaller than or equal to that number.

4. The ABC Mail Order Grocery sells artichokes for $2.05 per pound, beets for $1.15

per pound, and carrots for $1.09 per pound. It gives a 5% discount for orders of $100

or more before adding shipping costs. It charges $6.50 shipping and handling for any

order of 5 pounds or under, $14.00 shipping and handling for orders over 5 pounds and

under 20 pounds, and $14.00 plus $0.50 per pound for shipments of 20 pounds or more.

Write a program that uses a switch statement in a loop such that a response of a lets the

user enter the pounds of artichokes desired, b the pounds of beets, c the pounds of

carrots, and q allows the user to exit the ordering process. The program should keep

track of cumulative totals. That is, if the user enters 4 pounds of beets and later enters

5 pounds of beets, the program should report 9 pounds of beets. The program then

should compute the total charges, the discount, if any, the shipping charges, and the

total. The program then should display all the purchase information: the cost per pound,

the pounds ordered, and the cost for that order for each vegetable, the total cost of the

order, the discount (if there is one), the shipping charge, and the total of all the charges.

Submission Requirements: Use a folder to include all source files for each question.

For example, this lab contains three questions, so you need to create three folders, each

of which needs to save source files for each question. Then, you need to submit the

compressed file containing these folders to the Moodle platform.
