    Is this initialization of class variables and object setup correct usage?

    I am working on a console game and I am wondering if this is correct usage and setup of class objects, mainly in main, I think it's ok but idk, it just doesnt feel right, it feels like a kludge to me. It's not complete but this is what I have so far. These are not all of the classes either but this is the one i'm working on.


    #include "pch.h"
    #include <iostream>
    #include <string>
    #include <vector>
    #include "Item.h"
    #include "Player.h"
    #include "Arena.h"
    #include "Shop.h"
    #include "Dinosaur.h"
    int main()
        Shop shop;
        Arena arena;
        shop.AddItems("Golden Necklace of Speak Good", 450);
        shop.AddItems("Helmet of Protect Head", 800);
        shop.AddItems("Staff of Magic Stuff", 8000);
        shop.AddItems("Mask of Suffocation", 420);
        shop.AddItems("Dagger of Major Stabness", 230);
        Player player("Chay", 60000);
        std::vector<std::pair<std::string, int>> trexAttacks, velociraptorAttacks;
        //Create T-Rex
        trexAttacks.push_back(std::make_pair("Stomp", 80));
        trexAttacks.push_back(std::make_pair("Crunch", 30));
        Dinosaur Trex("T-Rex", 800, trexAttacks);
        std::cout << Trex.GetDinosaurName() << '\n';
        std::cout << "\n";
        //Create Velociraptor
        velociraptorAttacks.push_back(std::make_pair("JumpAttack", 20));
        velociraptorAttacks.push_back(std::make_pair("Bite", 15));
        Dinosaur Velociraptor("Velociraptor", 400, velociraptorAttacks);
        std::cout << Velociraptor.GetDinosaurName() << '\n';
        std::cout << "\n";
        //Show list of Arena opponents (All possible enemies the player could face)
        arena.CreateListOfOpponents(Trex, trexAttacks);
        arena.CreateListOfOpponents(Velociraptor, velociraptorAttacks);
        //Choose and enemy randomly
        std::cout << "\n";
        return 0;

            void ChooseRandomAttack()
                unsigned int chooseRandomAttack = rand() % mDinosaurAttacks.size();

                //If number is within certain range, perform attack.

    bump I've been told this is bad design? not really sure why though, they didnt specify, to me this was perfectly reasonable solution.

    Do you have one of these? If not, try creating one.

    A few minutes of sketching and reworking can save weeks of pointless code rewrites.

    > Dinosaur Trex("T-Rex", 800, trexAttacks);
    > arena.CreateListOfOpponents(Trex, trexAttacks);
    The second use of trexAttacks just seems wrong.
    If something wants to know about attacks, it should go through Dinosaur, not through Arena.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
