Question

 #2: Design and implement a program (name it CompareArrays) that compares the content of 2 single-dimensional arrays of the same size. The program prompts the users to enter the array size. Then prompts the user to initialize each array with integer values. The program defines method Compare() that takes two signal-dimensional arrays of type integer. The method compares the content of the arrays and returns true (Boolean type) if the arrays store same values in the same order. Otherwise, it returns false. The program main method calls method Compare()and prints the result from the method as shown below. Document your code and organized your output following these sample runs.

 

Sample run 1:

Array size:     4

First array:    23, -45, 78, 10

Second array:   23, -45, 78, 10
Judgment:       The arrays are identical

 

Sample run 2:

 

Array size:     5

First array:    78, 128, 300, 12, 300

Second array:   78, 128, 12, 300, 300
Judgment:       The arrays are not identical

 

Sample run 3:

 

Array size:     1

First array:    0

Second array:   0
Judgment:       The arrays are identical

 

 

#3: Design and implement a program (name it ArrayMethods), that defines 4 methods as follows:

 

int arrayMax(int[] arr) returns the maximum value in the an array

int arrayMin(int[] arr) returns the minimum value in an array

void arraySquared(int[] arr) changes every value in the array to its square (value²)

void arrayReverse(int[] arr) reverses the array (for example: array storing 7   8   9  becomes 9   8   7 )

 

The program main method creates a single-dimensional array of length 5 elements and initialize it with random integers between 1 and 100. The program displays the original array, then calls each of the above methods and displays their results as shown below. Document your code and organized your output following these sample runs.

 

Sample run 1:

 

Original array:  3, 5, 2, 6, 1

Max value:       6

Min value:       1

Squared array:   9, 25, 4, 36, 1

Reversed array:  1, 36, 4, 25, 9

 

Sample run 2:

 

Original array:  3, 2, 3, 7, 2

Max value:       7

Min value:       2

Squared array:   9, 4, 9, 49, 4

Reversed array:  4, 49, 9, 4, 9

 

Sample run 3:

 

Original array:  2, 2, 2, 2, 2

Max value:       2

Min value:       2

Squared array:   4, 4, 4, 4, 4

Reversed array:  4, 4, 4, 4, 4
