How do you access the element of 2-D array matrix

located at column 2 and row 4 (2 and 4 index numbers)?

Matrix {2} {4}; Matrix {4} {2}; Matrix [2] [4]; Matrix [4] [2];

Given the declaration and creation double [] alpha = new

double [75]; the valid range of index values for alpha is: 0

through 75 0 through 74 1 through 75 1 through 74 1

through 76 The search algorithm steps through an array,

comparing each item with the search value is called binary

search selection search. linear search. iterative search.

Which of the following are valid array declarations and

creations? [int] words = new words[10] char[] charArray =

\"Computer Engineering\"; char[] charArray = new

char[26]; double[3] nums = {3.5, 35.1, 32.0}; Assume

double[][] x = new double[4][5], what are x.[1]length and

x.length? 4 and 5 5 and 4 5 and 1 1 and 4 A one-

dimensional array is a list of related values with the

same___that is stored using a single group name. size

value data type parameter Given the declarations int [] x

= new int [200]; int [][] y = new int [75][5]; int [] z = new

int [80]; which of the following statements is true? x has

more components than y. y and z have the same number

of components. x and y have the same number of

components. y has more components than x. When you

return an array from a method, the method returns___. the

reference of the array a copy of the first element the

length of the array a copy of the array

Solution

Answers:

1)d

Reason:the first element indicates the rows and second

one indicate columns of an array.

2)b

Reason:valid range of an array is n-1 because the index is

starts from 0.

3)c

Reason:the elements in array are searched in the linear

manner or sequencial.thats why it is also called sequential

search.

4)c

Reason:it is valid declaration and creation of an array

5)b

6)c

Reason:you have to insert elements in an array of same

type.

7)d

Reason:because of it is two dimensional array it has more

components.

8)a

Reason:which means it contains the

referene(location/address of a that(datatype) typed array.
