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?
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: $$\begin{array}{llcc} \text { Make } & \text { Model } & \text { Year } & \text { cost } \\ \text { Ford } & \text { Taurus } & 2006 & \$ 21,000 \\ \text { Honda } & \text { Accord } & 2004 & \$ 11,000 \\ \text { Jeep } & \text { Wrangler } & 2007 & \$ 24,000 \end{array}$$
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.
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.
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}\\]
