Chapter 3: Problem 2

Write a definition statement for a character array large enough to hold any of the following strings: "Billy Bob's Pizza" "Downtown Auto Supplies" "Betty Smith School of Architecture" "ABC Cabinet Company"

Short Answer

Expert verified
Answer: The size of the character array needed is 34 characters, and the longest string is "Betty Smith School of Architecture".

Step by step solution

01

Find the length of the longest string

Compare the length of each given string and determine which one is the longest. Length of "Billy Bob's Pizza": 17 characters Length of "Downtown Auto Supplies": 23 characters Length of "Betty Smith School of Architecture": 33 characters Length of "ABC Cabinet Company": 19 characters From the above lengths, the longest string is "Betty Smith School of Architecture" with a length of 33 characters.
02

Define the character array

Add 1 to the length of the longest string to account for the null terminating character (\0). In this case, the array size would be 34 characters. Then, declare the character array with the determined size. ```c char companyName[34]; ``` The created character array 'companyName' can now hold any of the given strings, including the null terminating character.

Assume a program has the following variable definitions: int units; float mass; double weight; and the following statement: weight = mass * units; Which automatic data type conversion will take place? A) mass is demoted to an int, units remains an int, and the result of mass * units is an int. B) units is promoted to a float, mass remains a float, and the result of mass * units is a float. C) units is promoted to a float, mass remains a float, and the result of mass * units is a double.

Write a pseudocode algorithm for a program that calculates the total of a retail sale. The program should ask for the amount of the sale and the sales tax rate. The sales tax rate should be entered as a floating-point number. For example, if the sales tax rate is 6 percent, the user should enter \(0.06 .\) The program should display the amount of sales tax and the total of the sale. After you write the pseudocode algorithm, convert it to a complete \(\mathrm{C}_{++}\) program.
