Assume that array 1 and array 2 are both 25 -element integer arrays. Indicate whether each of the following statements is legal or illegal. A) arrayl \(=\) array 2 B) cout \(<<\) array 1 C) \(\operatorname{cin} \quad>>\) array 2
A weather analysis program uses the following array to store the temperature for each hour of the day on each day of a week. int temp [7] [ 24 ] ; Each row represents a day \((0=\text { Sunday, } 1=\text { Monday, etc. })\) and each column represents a time \((0=\text { midnight }, 1=1 \text { a.m., } \ldots, 12=\text { noon, } 13=1 \text { p.m., etc. })\) A) Write code to find Tuesday's average temperature. B) Write code to find the average weekly noon temperature.
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; // ' \(s^{\prime},\) ' \(h^{\prime},\) 'd', or 'c' struct PlayerStruct int playerNum; CardStruct card [5] PlayerStruct player [4]
Given the following array definition: \\[\text { int values }[5]=\\{4,7,6,8,2\\}\\] What does the following statement display? \\[\begin{aligned} \text { cout } &<<\text { values }[4]<<\text { " } \quad "<<(\text { values }[2]+\text { values }[3]) \\ &<<\quad \text { " } \quad<<++\text { values }[1]<<\text { endl } \end{aligned}\\]
Use the following car structure declaration to answer. struct Car string make, model ; int year ; double cost ; / / Constructors \(\operatorname{car}()\) \(\\{\text { make }=\text { model }=" " ; \text { year }=\operatorname{cost}=0 ; \\}\) Car (string mk, string md, int yr, double \(\\{\text { make }=\mathrm{mk} ; \text { model }=\mathrm{md} ; \text { year }=\mathrm{yr} ; \text { cost }=\mathrm{c} ;\\}\) Write a loop that will step through the array you defined in question \(29,\) displaying the contents of each element.
