问. 将一个数组的所有元素复制到另一个数组的程序。

2025年3月17日 | 阅读 3 分钟

说明

在此程序中，我们需要将一个数组的所有元素复制到另一个数组。这可以通过循环遍历第一个数组并将第一个数组的元素存储到第二个数组中的相应位置来完成。

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

算法

声明并初始化一个数组。
声明另一个与第一个数组大小相同的数组
从 0 到数组长度循环遍历第一个数组，并将第一个数组中的一个元素复制到第二个数组中，即 arr1[i] = arr2[i]。

解决方案

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]),

输出

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;
}

输出

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] + " ");
        } 
    }
}

输出

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] + " ");
        } 
    }
}

输出

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