Look at the following array definition. int numbers \([5]=\\{1,2,3\\}\) A) What value is stored in numbers [ \(2]\) ? B) What value is stored in numbers [ \(4]\) ?
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 \(\\{\text { make }=\mathrm{mk} ; \text { model }=\mathrm{md} ; \text { year }=\mathrm{yr} ; \text { cost }=\mathrm{c} ;\\}\) Define an array named forsale that holds 35 car structures. Initialize the first three elements with the following data: $$\begin{array}{llcc} \text { Make } & \text { Model } & \text { Year } & \text { cost } \\ \text { Ford } & \text { Taurus } & 2006 & \$ 21,000 \\ \text { Honda } & \text { Accord } & 2004 & \$ 11,000 \\ \text { Jeep } & \text { Wrangler } & 2007 & \$ 24,000 \end{array}$$
Look at the following array definition. double sales [8][10] A) How many rows does the array have? B) How many columns does the array have? C) How many elements does the array have? D) Write a statement that stores 3.52 in the last column of the last row in the array.
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.
Look at the following array definition. int values[10]; A) How many elements does the array have? B) What is the subscript of the first element in the array? C) What is the subscript of the last element in the array? D) If an int uses four bytes of memory, how much memory does the array use?
