A two-dimensional array can be viewed as _____ and _____.

one

A two-dimensional array can have elements of ____________ data types.

several identical arrays

A two-dimensional array is like _____ put together.

All of these

A two-dimensional array of characters can contain ______________.

null terminator

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

elements

The individual values contained in an array are known as

Memory address

The name of an array stores the ______ of the first array element.

range variable

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

implicit array sizing

The statement: int grades[ ] = { 100, 90, 99, 80}; shows an example of:

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

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

It creates a vector object with a starting size of 10 and all elements are initialized with the value 2. Answer: D

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

4

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

3 5

What will the following C++ 11 code display? vector<int> numbers { 3, 5 }; for (int val : numbers) cout << val << endl;

0

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

87 66 55

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

An error will occur when the code runs

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

all but the first dimension

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

int array[10];

Which of the following has a valid c++ array definition?

int scores [10];

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

vector<int> v;

Which statement correctly defines a vector object for holding integers?

vector<int> n { 10, 20 };

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

initialization list

An ________________ can be used to specify the starting values of an array.

for loop

An array can easily be stepped through by using a

the same data type

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

string names[5];

An array of string objects that will hold 5 names would be declared using which statement

illegal in C++

An array with no elements is ________

constant integer expression,zero

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

the row subscript of the element, the column subscript of the element

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

initialized, declared

Arrays may be __________ at the time they are ___________

subscript

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

scores[2]

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

1000

How many elements does the following array have?

you must furnish an initialization list

If you leave out the size declarator in an array definition:

legal in C++

It is ____________ to pass an argument to a function that contains an individual array element, such as numbers[3].

begins with zero

Subscript numbering in C++

push_back

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

pop_back

This vector function removes an item from a vector

size

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

empty

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

subscript

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

a loop to assign the elementsofonearraytotheoherarray

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

name

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

FALSE

True/False: An array initialization list must be placed on one single line.

FALSE

True/False: Assume array1 and array2 are the names of arrays. To assign the contents of array2 to array1, you would use the following statement. array1 = array2;

FALSE

True/False: C++ limits the number of array dimensions to two.

FALSE

True/False: If you attempt to store data past an array's boundaries, it is guaranteed that the compiler will issue an error.

FALSE

True/False: The statement: double money[25.00]; is a valid C++ array definition.

TRUE

True/False: When you pass an array as an argument to a function, the function can modify the contents of the array.

arrays

Unlike regular variables, these can hold multiple values.
