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

  1. Declare and initialize an array.
  2. Declare another array of the same size as of first one
  3. 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].

Input:

arr1 = [1, 2, 3, 4, 5];  

arr2 = [None] * len(arr1);  

Output:

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

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

        //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] + " ");  
        }
