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] :
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.
In a program you need to store the identification numbers of 10 employees (as ints) and their weekly gross pay (as doubles). A) Define two arrays that may be used in parallel to store the 10 employee identification numbers and 10 weekly gross pay amounts. B) Write a loop that uses these arrays to print each employee's identification number and weekly gross pay.
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]
In a program you need to store the names and populations of 12 countries. Create an appropriate array to store this information and then write the code needed to read the information into the array from a file named pop.dat.
