legal in C++

The name of an array stores the __________ of the first array element

memory address

To pass an array as an argument to a function, pass the __________ of the array

name

The __________ is automatically appended to a character array when it is initialized with a string constant

null terminator

A two-dimensional array can have elements of __________ data type(s)

one

Which statement correctly defines a *vector* object for holding integers?

vector<int> v;

Which statement correctly uses C++11 to initalize a *vector* of *ints* named *n* with the values *10* and *20*?

vector<int>n{10,20};

What will the following code display? *int numbers[4] = {99, 87}; cout << numbers[3] << endl;*

0

How many elements does the following array have? *int values[1000];*

1000

What is the last legal subscript that can be used with the following array? *int values[5];*

4

What will the following code display? *int numbers[ ] = {99, 87, 66, 55, 101};* *cout << numbers[3] << endl;*

55

What will the following code display? *int numbers[ ] = {99, 87, 66, 55, 101}; for (int i = 1; i < 4; i++) cout << numbers[i] << " ";*

87 66 55

What does the following code do? *const int SIZE = 5; double x[SIZE]; for (int i = 2; i <= SIZE; i++) { x[i] = 0.0; }

An error will occur when the code runs.

Subscript numbering in C++

begins with zero

What does the following statement do? *vector<int> v(10, 2);*

It creates a vector object with a starting size of 10 and initializes all the elements with the value 2.

What does the following statement do? *vector<int> v(10);*

It creates a vector object with a starting size of 10.

An array can easily be stepped through by using a

a for loop

To assign the contents of one array to another, you must use

a loop to assign the elements of one array to the other array

When writing functions that accept multi-dimensional arrays as arguments, __________ must be explicitly stated in the parameter list

all but the first dimension

This following statement shows an example of ___________ *int grades][ ] = {100, 90, 99, 80};*

an illegal array declaration, or an illegal array initialization

Unlike regular variables, __________ can hold multiple values

arrays

An array's size declarator must be a __________ with a value greater than __________

constant integer expression, zero

The individual values contained in an array are known as

elements

This *vector* function returns *true* if the *vector* has no elements

empty

An array with no elements is

illegal in C++

A(n) __________ can be used to specify the starting values of an array

initialization list

Arrays must be __________ at the time they are __________

initialized, declared

Which of the following is a valid C++ array definition?

int scores[25];

Which of the following is a valid C++ array definition?

int sizes[10];

This *vector* function removes an item from a *vector*

pop_back

This *vector* function is used to insert an item into a *vector*

push_back

A two-dimensional array can be viewed as

rows and columns

Given the following declaration, where is the value 77 stored in the *scores* array? *int scores[] = {83, 62, 77, 97, 86}*

scores[2]

This *vector* function returns the number of elements in a *vector*

size

An array of *string* objects that will hold five names would be declared with which of the following statements?

string names[5];

A two-dimensional array of characters can contain

strings of the same length, strings of different lengths & uninitialized elements

By using the same ___________ you can build relationships between data stored in two or more arrays

subscript

To access an array element, use the array name and the element's ___________

subscript

The range-based *for* loop in C++11 is designed to work with a built-in variable known as

the range variable

An element of a two-dimensional array is referred to by

the row subscript of the element followed by the column subscript of the element

An array can store a group of values, but the values must be

the same data type

If you leave out the size declarator in an array definition

you must furnish an initialization list
