Comparing between classes

i got an class which creates numbers between 1-6 and another class which puts them into an array. How can i compare two arrays if they are the same? (so the commented line would work)

#include <iostream>
#include <ctime>
#include <cstdlib>

class dice {
private:
    unsigned int number;
public:
    dice() {
        (*this).number = (rand() % 6) + 1;
        return;
    }
};

class dicemng {
private:
    unsigned int dice_count;
    dice* arr_dice;
public:
    dicemng(unsigned int k = 0) : dice_count(k) {
        arr_dice = new dice[dice_count];
        return;
    }
};

int main() {

    srand(time(nullptr));
    dicemng w1(5), w2(5);
    //std::cout << (w1 == w2) << std::endl;

    return 0;
}

Thanks for any help!
