TCC Displays the Total Cost of His Order Program
Chapter 3 Pg 72 Exercise 4
Aaron Lakely is going to the grocery store to buy some bananas and apples,
both of which are sold by the pound. He wants a program that calculates and
displays the total cost of his order, including a 3% sales tax. First, create
an IPO chart for this problem, and then desk-check the algorithm twice. For
the first desk-check, use 2 and 3.5 as the number of pounds of bananas and
apples, respectively. And use $0.99 and $1.89 as the price per pound of
bananas and apples, respectively. For the second desk-check, use your own set
of data. After desk-checking the algorithm, list the input, processing, and
output items in a chart similar to the one shown in Figure 3-25, and then
enter the appropriate C++ declaration statements
.Chapter 3 Pg 72 Exercise 6
Builders Inc. wants a program that allows its salesclerks to enter the
diameter of a circle and the price of railing material per foot. The program
should calculate and display the total price of the railing material. Use
3.1416 as the value of pi. First, create an IPO chart for this problem, and
then desk-check the algorithm twice. For the first desk-check, use 35 feet as
the diameter and $2 as the price per foot. For the second desk-check, use 15.5
and $3.50. After desk-checking the algorithm, list the input, processing, and
output items in a chart similar to the one shown in Figure 3-25, and then
enter the appropriate C++ declaration statements.
Chapter 4 Pg 107 Exercise 11
Jacob Weinstein wants a program that displays his savings account balance at
the end of the month, given the beginning balance, total deposits, and total
withdrawals.
a. Using the chart shown earlier in Figure 4-12 as a guide, enter the input,
processing, and output items, as well as the algorithm, in the first column.
b. Desk-check the algorithm twice. For the first desk-check, use 2545.75,
409.43, and 210.65 as the beginning balance, total deposits, and total
withdrawals. For the second desk-check, use 1125.33, 23, and 800.94.
c. Enter the C++ instructions in the second column of the chart, and then
desk-check the program using the same data used to desk-check the algorithm.
d. If necessary, create a new project named Introductory11 Project, and save
it in the Cpp8Chap04 folder. Enter your C++ instructions into a source file
named Introductory11.cpp. Also enter appropriate comments and any additional
instructions required by the compiler. Test the program using the same data
used to desk-check the program.
Chapter 4 Pg 108 Exercise 14
Silvia’s Pizzeria sells four different sizes of pizzas: small, medium, large,
and family. The manager of the pizzeria wants a program that displays the
total number of pizzas sold, as well as the percentage of the total number
contributed by each different size.
a. Using the chart shown earlier in Figure 4-12 as a guide, enter the input,
processing, and output items, as well as the algorithm, in the first column.
b. Desk-check the algorithm twice. For the first desk-check, use 25, 50, 50,
and 75 as the numbers of small, medium, large, and family pizzas. For the
second desk-check, use 30, 25, 85, and 73. Record the percentages with one
decimal place.
c. Enter the C++ instructions in the second column of the chart, and then
desk-check the program using the same data used to desk-check the algorithm.
d. If necessary, create a new project named Intermediate14 Project, and save
it in the Cpp8Chap04 folder. Enter your C++ instructions into a source file
named Intermediate14.cpp. Also enter appropriate comments and any additional
instructions required by the compiler. Test the program using the same data
used to desk-check the program
