Chapter 8: Problem 23

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 [ \(4]\) ?

Short Answer

Expert verified
Answer: For the given array 'numbers', the value stored at index 2 is 3, and the value stored at index 4 is 0.

Step by step solution

01

Examine the array's given values

We have an array initialized as follows: int numbers[5] = {1, 2, 3}; The indices and values are: Index 0 -> Value 1 Index 1 -> Value 2 Index 2 -> Value 3
02

Find the value at index 2

Since we already have the values for indices 0, 1, and 2 from the given array, we can simply state that: The value stored at index 2 of the numbers array is 3. So, the answer for part A is 3.
03

Find the value at index 4

We don't have a given value for index 4, as the given array only has 3 values. In this case, the compiler will automatically initialize the remaining elements to zero. The value stored at index 4 of the numbers array is 0. So, the answer for part B is 0.

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

To define a two-dimensional array, _________ size declarators are required.

You cannot use the _________ operator to copy data from one array to another in a single statement.

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.

Each element of an array is accessed and indexed by a number known as a(n) _________.
