Chapter 8: Problem 29

Use the following Car structure declaration to answer questions \(28-30\). struct Car string make model: Int year: double cost: // Constructors \(\operatorname{Car}()\) { make \(=\) model \(=" " ;\) year \(=\cos t=0: 1\) } Car(string mk, string md. int yr, double c) { make \(=\) whe model \(=\) ind : year \(=y r ; \quad \cos t=c: 1\)} Define an array named for Sale that holds 35 Car structures. Initialize the first three elements with the following data: $$\begin{array}{llll} \text { Make } & \text { Model } & \text { Year } & \text { cost } \\ \text { Ford } & \text { Taurus } & 2002 & \$ 21,000 \\ \text { Honda } & \text { Accord } & 2001 & \$ 11,000 \\ \text { Jeep } & \text { Wrangler } & 2004 & \$ 24,00000 \end{array}$$

Short Answer

Expert verified
Answer: To create an array with 35 Car structures, declare it as "Car forSale[35];". Then, initialize the first three elements using their respective constructors: 1. forSale[0] = Car("Ford", "Taurus", 2002, 21000); 2. forSale[1] = Car("Honda", "Accord", 2001, 11000); 3. forSale[2] = Car("Jeep", "Wrangler", 2004, 24000);

Step by step solution

01

Create an array of Car structures

To create an array that holds 35 Car structures, use "Car forSale[35];".
02

Initialize the first element

Use the constructor with all parameters provided to initialize the first element of the array: "forSale[0] = Car("Ford", "Taurus", 2002, 21000);".
03

Initialize the second element

Use the constructor with all parameters provided to initialize the second element of the array: "forSale[1] = Car("Honda", "Accord", 2001, 11000);".
04

Initialize the third element

Use the constructor with all parameters provided to initialize the third element of the array: "forSale[2] = Car("Jeep", "Wrangler", 2004, 24000);".

Most popular questions from this chapter

Diagrams are an important means of clarifying many programming concepts. You have seen them used throughout this book to illustrate such things as how the flow of control works for various programming constructs, how a program is broken into modules and those modules related, how data is stored in memory, and how data is organized. Here is a set of declarations that define how the data for a set of poker hands is organized. Create a neat diagram that illustrates this organization. The diagram in Section 7.4 of Chapter 7 on nested structures might give you an idea of how to begin. struct CardStruct Int face: char suit: \(\quad / /\) 's' \(,\) 'h', 'd', or 'c' struct Playerstruct int playerNum; CardStruct card [5] P1ayerStruct player [4]

By using the same ______ for multiple arrays, you can build relationships between the data stored in the arrays. These arrays are referred to as parallel arrays.

How do you establish a parallel relationship between two or more arrays?

Use the following Car structure declaration to answer questions \(28-30\). struct Car string make model: Int year: double cost: // Constructors \(\operatorname{Car}()\) { make \(=\) model \(=" " ;\) year \(=\cos t=0: 1\) } Car(string mk, string md. int yr, double c) { make \(=\) whe model \(=\) ind : year \(=y r ; \quad \cos t=c: 1\)} Write a loop that will step through the array you defined in question 29 , displaying the contents of each element.

Each of the following functions contains errors, Locate as many as you can. A) void showValues (Int nums) for (Int count = 0; count < 8; count++) cout \(\langle\langle\text { nums }[\text { count }]\) B) void showValues (int nums \([4][])\) for \((\text { rovs }=0: \text { rows }\langle 4: \text { rows++})\) For \((\operatorname{cols}=0: \operatorname{cols}<5: \operatorname{cols}++)\) cout \(<<\) nums [rows] [cols] :
