C++ Ch. 7 Arrays, Vectors

____________ are data structures consisting of related data items of the same type

Arrays are always _______ structures because they remain the same size throughout execution

Character arrays can also represent ________ (hint: types)

An array is a _____________ group of memory locations that all have the same type.

To refer to a particular location or element in the array, we specify the name of the array and the position  _______ of the particular element.

The position number is more formally called a subscript or index (this number specifies the number of elements from the beginning of the array).

• True

• False

The first element in every array has subscript ______ and is sometimes called the _____th element.

A subscript/index must be an integer or integer expression (using any integral type).

• True

• False

Brackets ' [ ' have a higher precedence than ' ( '

• True

• False

[ ] and ( ) have the highest precedence

• True

• False

In order to declare an array of a certain size, you must indicate three things. Check all that apply

• Type

• Name

• Array Size

• Element Initializer List

• All of the above

At ___________ , the compiler reserves the appropriate amount of memory (arrays).

• Run time

• Program termination

• The middle point of execution

• Compilation

It is good practice to declare more than one array per declaration to enhance readability.

• True

• False

Which of the following is an array declaration with initalizers

• Int n[ 10 ];

• Int *n;

• Int &n = 10;

• Int n[10] = { 1, 2, 3, 4, 5 };

What is the most dominant method for accessing and printing an entire array.

• IF

• WHILE

• IF ELSE

• FOR

• None of the above

This statement will not compileint array[] = {1, 2, 3, 4};

• True

• False

If the array size is omitted from a declaration with an initializer list, the compiler determines the number of elements in the array by counting the number of elements in the initializer list.

• True

• False

If the array size is omitted from a declaration with an initializer list, the compiler determines the number of elements in the array by accessing the closest constant integer to the statement.

• True

• False

Int n[11];How many possible elements can be stored in this array?

• 12

• 10

• 11

• 9

Int n[11];What is the last index number (or subscript) of this array?

• 11

• 12

• 9

• 10

• None of the above

Providing more initializers in an array initializer list than there are ___________ in the array is a compilation error.

What is wrong with this code?int SIZE = 7;int array[ SIZE ];

• Size does not need to be declared

• Size should be declared as type double

• Size should be declared as a constant

• Nothing

Not assigning a value to a constant variable when it is declared....

• Will allow you to modify it during program execution

• Will take on a random value when called

• Will cause a compilation error

• Does not matter because it will allow for modification later

Const int x;x = 7;Will this compile?

• Yes

• No

Only constants can be used to declare the size of automatic and status arrays. Not using a constant for this purpose is a compilation error.

• True

• False

Defining the size of each array as a constant variable instead of a literal constant can make programs less scalable.

• True

• False

In the statement:int a [ arraySize ] = { 87, 64, 52, 4, 45, 63, 55, 22, 78 };What is the element that is in the 7th index position?

• 55

• 22

• 63

• 78

Which is the array name?int int1[ int2 ];

• Int

• Int1

• Int2

A program initializes static local arrays when their declarations are ____________.

• First encountered

• Accessed

• Terminated

• Created

If a static array is not initialized explicitly by you, the program will not compile

• True

• False

If a static array is not initialized explicitly by you, each element of that array is initialized to zero by the compiler when the array is created.

• True

• False

This is a static arrayint n[];

• True

• False

Applying 'static' to an array declaration will allow the array not to be created and initialized each time a program calls a function containing the array.

• True

• False

Static int array1[ arraySize];Will initialize each element to 0 the first time it is called.

• True

• False

Void function1( array[] );This function will operate correctly, receiving values from the array.

• True

• False

Void function1( array ); This function will operate correctly, receiving values from the array.

• True

• False

When passing an array to a function, the array size is normally passed as well, so the function can process the specific number of elements in the array.

• True

• False

C++ passes arrays to functions by reference—the called functions can modify the element values in the callers’ original arrays.

• True

• False

C++ passes arrays to functions by value—the called functions can modify the element values in the callers’ original arrays.

• True

• False

The name of the array is the address in the computers memory of the first element of the array

• True

• False

The value of the name of the array is the address in the computer’s memory of the first element of the array.Because the starting address of the array is passed, the called function knows precisely where the array is stored in memory.

• True

• False

Pass by value means that the calling function can read and write to the original values.

• True

• False

Pass by reference means that the calling function can read and write to the original values.

• True

• False

Passing arrays by value would mean that each element would be copied to the calling function, thus causing a penalty in performance speeds.

• True

• False

Although entire arrays are passed by reference, individual array elements are passed by value exactly as simple variables are.

• True

• False

To pass an element of an array to a function, use the array name as an argument in the function call.

• True

• False

The linear search compares each element of an array with a __________

_________ sort is a simple, but inefficient, sorting algorithm.
