Problem with function returning a structure

I'm trying to write a simple text based RPG. This is the pertinent code:

Code:

---

//=========================================
//PitII- Text based RPG
//01-20-07 to __-__-__
//=========================================
//INCLUDES
#include <iostream>
#include <string>
#include <vector>
#include <ctime>

//USING
using namespace std;

//FUNCTIONS
void clear();
string begin_game();
int new_room();
struct weapon create_new_weapon(int char_lvl, int mon_lvl);

//THE SAD, LONELY, choice
char choice;

int main()
{
        //Classes for use throughout the ENTIRE GAME
        struct weapon
        {
                string name;
                int min;
                int max;
                int bonus;
        };
        struct armor
        {
                string name;
                int def;
                int block;
        };
        class Monster
        {
        public:
                string name;
                int lvl;
                int hp;
                int hp_max;
                int mind;
                int maxd;
                int armor;
                int block;
        };
        class Hero
        {
        public:
                string name;
                int hp;
                int hp_max;
                string weapon_name;
                int mind;
                int maxd;
                string armor_name;
                int armor;
                int block;
                int lvl;
                int exp;
                int exp_need;
                void show_stats()
                {
                        cout<<name<<":\n"
                                <<"\tHealth:  "<<hp<<"/"<<hp_max<<"\n"
                                <<"\tLevel:  "<<lvl<<"\n"
                                <<"\tExp/Need:"<<exp<<"/"<<exp_need<<"\n"
                                <<weapon_name<<":\n"
                                <<"\tDamage:  "<<mind<<"-"<<maxd<<"\n"
                                <<armor_name<<":\n"
                                <<"\tArmor:  "<<armor<<"\n"
                                <<"\tBlock%:  "<<block<<"%\n";
                        cout<<"Press any key to continue.\n>:";
                        cin>>choice;
                };
        };


        //Begin Game:
        Hero player;
        player.hp = 50;
        player.hp_max = 50;
        player.weapon_name = "Rusty Dagger";
        player.mind = 1;
        player.maxd = 3;
        player.armor_name = "Cloth Armor";
        player.armor = 15;
        player.block = 5;
        player.exp = 0;
        player.exp_need = 100;
        player.lvl = 1;
        player.name = begin_game();
        cout<<player.name<<" has entered the pit.\n>:";
        clear();

        //Display stats, setup and display items
        player.show_stats();

        //Begin of Game Loop
        srand(time(NULL));
        do
        {
                clear();
                create_new_weapon(2, 7);
                cin>>choice;
        }while(player.hp >= 1);
        return 0;
}

struct weapon create_new_weapon(int char_lvl, int mon_lvl)
{
        cout<<"A blacksmith forged you a weapon!"<<"\n"
                <<"Sword, level "<<char_lvl + mon_lvl<<"\n";
        weapon new_weapon;
        new_weapon.name = "Sword";
        new_weapon.min = 52;
        new_weapon.max = 67;
        new_weapon.bonus = 5;
        return new_weapon;
}

What it is supposed to do is create a new weapon based on character and monster level, but it returns a miriad of errors-
C2027: use of undefined type 'weapon'
C2079: 'create_new_weapon' uses undefined struct 'weapon'
C2079: 'new_weapon' uses undefined struct 'weapon'
C2228: left of '.name' must have class/struct/union (for all of the things)
What's wrong?

You don't declare structs or classes inside main(). You do it outside main(). Likewise, you don't declare that sad, lonely char outside main--you do it inside main().

Next time when you have errors, make sure you do this:

Code:

---

weapon new_weapon;  //ERROR***ERROR****ERROR

---

struct weapon should be defined before you firstly use with name
