Copy string without using strcpy()

#include <iostream>
using namespace std;

int main(){

    char arr1[100],arr2[100];
    int i;

    cout<<"Enter string"<<endl;
    cin>>arr1;

    for( i=0; arr1[i] != '\0'; ++i)
    {
        arr2[i] = arr1[i];
    }
    arr2[i] = '\0';

    cout<<arr1<<" = Array 1 String"<<endl;
    cout<<arr2<<" = Array 2 string Copied"<<endl;
    return 0;
