Deck 8: Arrays

Question 1

An atomic variable is also referred to as a scalar variable.

Answer 1

True

Question 2

A data structure is also known as an atomic data type.

Answer 2

False

Question 3

The values of a data structure can be decomposed into individual data elements, each of which has to be atomic.

Answer 3

False

Question 4

A one-dimensional array is also known as both a single-dimensional array and a single-subscript array.

Question 5

An array component is also referred to as the element's subscript value.

Question 6

Each individual element in an array is referred to as an indexed variable.

Question 7

The computer uses the index as an offset from the array's starting position.

Question 8

Atomic data types can be decomposed into simpler types.

Question 9

Structured types can be decomposed into simpler types that are related within a defined structure.

Question 10

A double-precision variable may never be used as a subscript.

Question 11

The statement scanf("%d %lf", grades[0], price[2]); causes two values to be read and stored in the variables grades[0] and price[2].

Question 12

The LISP language was developed specifically for manipulating lists.

Question 13

When using an array element, C performs bound checks on the value of the index.

Question 14

If an array has been declared as consisting of 10 elements and you use an index of 12, C will notify you of the error when the program is compiled.

Question 15

Arrays can be declared either within or outside a function.

Question 16

Arrays declared outside a function have global scope.

Question 17

Global arrays can only be static.

Question 18

When first created, the values within auto local arrays are undefined.

Question 19

When passing an array to a function, the called function receives a copy of the array; this is because C uses pass by value.

Question 20

For large arrays, making duplicate copies of the array for each function call would waste computer storage, consume execution time, and frustrate the effort to return multiple element changes made by the called program.

Question 21

It is generally advisable to omit the size of the array in a function header line.

Question 22

A one-dimensional array consists of both rows and columns of elements.

Question 23

The outer braces in the initialization statement of a two-dimensional array can be omitted.

Question 24

Nested loops are especially useful when dealing with two-dimensional arrays because they allow the programmer to easily cycle through each element.

Question 25

In a three-dimensional array, the second subscript is often called the rank.

Question 26

Arrays of three, four, five, six, or more dimensions can be viewed as mathematical n-tuples of order three, four, five, six, and so on, respectively.

A)data structure
B)scalar data type
C)array

A)while
B)do-while
C)switch
D)for

Question 37

All ____ arrays are created and destroyed each time the function they are local to is called and completes its execution.

A)global
B)static
C)auto
D)extern
