Program to copy all the elements of one array into another array

Q. Program to copy all the elements of one array into another array.

Explanation

In this program, we need to copy all the elements of one array into another. This can be accomplished by looping through the first array and store the elements of the first array into the second array at the corresponding position.

Algorithm

Declare and initialize an array.
Declare another array of the same size as of first one
Loop through the first array from 0 to length of the array and copy an element from the first array to the second array that is arr1[i] = arr2[i].

Solution

Python

  #Initialize array   arr1 = [1, 2, 3, 4, 5];      #Create another array arr2 with size of arr1  arr2 = [None] * len(arr1);     #Copying all elements of one array into another  for i in range(0, len(arr1)):      arr2[i] = arr1[i];      #Displaying elements of array arr1   print(“Elements of original array: “);  for i in range(0, len(arr1)):     print(arr1[i]),     print();     #Displaying elements of array arr2   print(“Elements of new array: “);  for i in range(0, len(arr2)):     print(arr2[i]),  

Output:

Elements of original array:   1 2 3 4 5   Elements of new array:   1 2 3 4 5

C

  #include <stdio.h>     int main()  {      //Initialize array       int arr1[] = {1, 2, 3, 4, 5};            //Calculate length of array arr1      int length = sizeof(arr1)/sizeof(arr1[0]);            //Create another array arr2 with the size of arr1.        int arr2[length];            //Copying all elements of one array into another      for (int i = 0; i < length; i++) {           arr2[i] = arr1[i];       }              //Displaying elements of array arr1       printf(“Elements of original array: n”);      for (int i = 0; i < length; i++) {           printf(“%d “, arr1[i]);      }            printf(“n”);            //Displaying elements of array arr2       printf(“Elements of new array: n”);      for (int i = 0; i < length; i++) {           printf(“%d “, arr2[i]);      }      return 0;  }  

Output:

Elements of original array:   1 2 3 4 5   Elements of new array:   1 2 3 4 5

JAVA

  public class CopyArray {      public static void main(String[] args) {                        //Initialize array           int [] arr1 = new int [] {1, 2, 3, 4, 5};                     //Create another array arr2 with size of arr1          int arr2[] = new int[arr1.length];                    //Copying all elements of one array into another          for (int i = 0; i < arr1.length; i++) {               arr2[i] = arr1[i];           }                      //Displaying elements of array arr1           System.out.println(“Elements of original array: “);          for (int i = 0; i < arr1.length; i++) {              System.out.print(arr1[i] + ” “);          }                     System.out.println();                    //Displaying elements of array arr2           System.out.println(“Elements of new array: “);          for (int i = 0; i < arr2.length; i++) {              System.out.print(arr2[i] + ” “);          }       }  }  

Output:

Elements of original array:   1 2 3 4 5   Elements of new array:   1 2 3 4 5

C#

  using System;                        public class CopyArray  {      public static void Main()      {          //Initialize array           int [] arr1 = new int [] {1, 2, 3, 4, 5};                     //Create another array arr2 with size of arr1          int [] arr2 = new int[arr1.Length];                    //Copying all elements of one array into another          for (int i = 0; i < arr1.Length; i++) {               arr2[i] = arr1[i];           }                      //Displaying elements of array arr1           Console.WriteLine(“Elements of original array: “);          for (int i = 0; i < arr1.Length; i++) {              Console.Write(arr1[i] + ” “);          }                     Console.WriteLine();                    //Displaying elements of array arr2           Console.WriteLine(“Elements of new array: “);          for (int i = 0; i < arr2.Length; i++) {              Console.Write(arr2[i] + ” “);          }       }  }  

Output:

Elements of original array:   1 2 3 4 5   Elements of new array:   1 2 3 4 5

PHP

  <!DOCTYPE html>  <html>  <body>  <?php  //Initialize array   $arr1 = array(1, 2, 3, 4, 5);      //Create another array arr2  $arr2 = array();            //Copying all elements of one array into another  for ($i = 0; $i < count($arr1); $i++) {       $arr2[$i] = $arr1[$i];   }       //Displaying elements of array arr1   print(“Elements of original array: <br>”);  for ($i = 0; $i < count($arr1); $i++) {      print($arr1[$i] . ” “);  }      print(“<br>”);     //Displaying elements of array arr2   print(“Elements of new array: <br>”);  for ($i = 0; $i < count($arr2); $i++) {      print($arr2[$i] . ” “);  }   ?>  </body>  </html>
