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.

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.

You can use Eclipse later for program verification after submission. 1. Create an abstract Animal class. Then, create a Cat class. Please implement all the methods and inheritance relations in the UML correctly: Animal name: String # Animal (name: String) + getName(): String + setName(name: String): void + toString(): String + makeSound(): void Cat breed : String age: int + Cat(name: String, breed: String, age: int) + getBreed(): String + getAge (): int + toString(): String + makeSound(): void 2. Create a public CatTest class with a main method. In the main method, create one Cat object and print the object using System.out.println(). Then, test makeSound() method. Your printing result must follow the example output: name: Coco, breed: Domestic short-haired, age: 3 Meow Meow

automata theory can please wright the exact language it know for example say it knows strings start 0 and end with 1 this is as example also as regular expression
