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

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.
