Chapter 7.7, Problem 7.14CP
Program Plan Intro

Copying one array to another array:

An array is the variable which stores the same types of data. To copy the data from one array to another, first initialize the two arrays with their respective element sizes.

  • Consider one of the arrays is filled with a set of values and the filled array is required to be copied to another array.
  • To copy the content of one array to another, assign each element of the array to another by using the equal to (“=”) operator.
    • Each element of the array can be referred to by using index numbers of the array.

Example:

Consider the following code which performs the copying of array elements.

// Header file section

#include<iostream>

using namespace std;

// Main function definition

int main()

{

// Declaring the arrays

int list1[5];

int list2[5];

//Declare the variables

int n, i;

/* Prompt the user to enter the number of elements

need to be copied */

cout << "Enter the number of elements need to be copied" << endl;

// Read “n” value from the user

cin >> n;

/* Execute the for loop to include the elements in the list1[]*/

for (i = 0; i < n; i++)

{

cin >> list1[i];

}

// Copying of one array to another

/* Execute the for loop to copy the elements from

list1[] to list2[]*/

for (i = 0; i < n; i++)

{

//Copying each element of the array to another

list2[i] = list1[i];

}

// Print the header

cout << "copied array" << endl;

/* Execute the for loop to print the elements in the

list2[]*/

for (i = 0; i < n; i++)

{

cout << list2[i] << endl;

}

}

Explanation:

Thus, in the above example, the two arrays are first initialized with the elements and then one array is assigned to another array using the equal to “=” operator. But, this equal to operator does not copy the content alone; it is used for assignment.

JAVA PROGRAM Chapter 7. PC #16. 2D Array Operations Write a program that creates a two-dimensional array initialized with test data. Use any primitive data type that you wish. The program should have the following methods: • getTotal. This method should accept a two-dimensional array as its argument and return the total of all the values in the array. • getAverage. This method should accept a two-dimensional array as its argument and return the average of all the values in the array. • getRowTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row. • getColumnTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the…
