Accessing Class objects to compare with global variables - c++

Question

Im making a text store menu. I have a basic weapon class with a string for name and weapon sound, a bool for if you already own the item or not and a double for the price.
I'm trying to compare the double price in the class to the global variable p_balance (players balance) to
check if the player can afford the item
Here's the class
class Weapon
{
public:
string name, sound;
bool owned = false;
double price;
public:
Weapon() //Default Constructor
{
name = "name";
sound = "sound";
owned = owned;
price = 0;
}
Weapon(string i_name, string i_sound, bool i_owned, double i_price)//Constructor
{
name = i_name;
sound = i_sound;
owned = i_owned;
price = i_price;
void displayItems();
{
cout << name << " - " << price << "g." << endl;
}
}
};
(i know i know i should switch Weapon Weapons[i] to Weapon weapons[i] to make my life easier)
And here's my most recent attempt at accessing it
while (p_balance < Weapons[0].getPrice()) // Not enough gold
{
cout << "Sorry, it seems you don't have enough gold." << endl;
goto MainMenu;
}
I had tried to make a method within the class to get the price but that didnt work out, but thats why its calling on a method that doesnt exist
I've also toyed around with if loops but the were getting messy and displaying more info than i liked
After the owner money check, i have it perform a ownership check and check if something equipped to that items slot, but when I used nested if statements it displayed the result of all of them even if the first if (price) was failed so I figured maybe a while statement?
I'm not looking for the answer cause I want to learn but last time I posted here I got some great hints that really helped me out and I'm hitting the point of frustration with this so I figured I'd ask for help!
EDIT:
I took what you guys said into account and went back to the pseudo.
I'm quite pleased with how it is now:
#include <iostream>
#include <string>
using namespace std;
int p_choice;
double p_balance = 125;
//Simple Weapon Class
class Weapon
{
public:
int slot;
string name, sound;
bool owned = false;
double price;
public:
Weapon() //Default Constructor
{
slot = 0;
name = "name";
sound = "sound";
owned = owned;
price = 0;
}
Weapon(int i_slot, string i_name, string i_sound, bool i_owned, double i_price)//Constructor
{
slot = i_slot;
name = i_name;
sound = i_sound;
owned = i_owned;
price = i_price;
double* p_ptr;
p_ptr = &price;
void displayItems();
{
int x = 0;
cout << slot << " - " << name << " - " << price << "g." << endl;
}
}
};
int main()
{
int p_selection;
bool hasWeapon, offHand, inStore;
hasWeapon = false;
offHand = false;
inStore = true;
//Weapon Array
cout << "---------------------------------------------" << endl;
Weapon Weapons[6];
Weapons[0] = Weapon(1, "Great Sword of Greatening", "Tssng", false, 50);
Weapons[1] = Weapon(2, "Claw", "Thwack", false, 10);
Weapons[2] = Weapon(3, "Silent Pea-shooter", "Pew Pew", false, 15);
Weapons[3] = Weapon(4, "Loudening Silencer Attachment", "...", false, 5);
Weapons[4] = Weapon(5, "Tiger-Repelling Rock ", "Meooowraaarah", false, 25);

//Menu
do
{
cout << "1. Buy" << endl;
cout << "2. Check Balance" << endl;
cout << "3. Exit" << endl;
cin >> p_choice;
if (p_choice == 1)
{
//Ask player which weapon the want to buy
cout << "Which item are you interested in?" << endl;
cout << "(Choose using 1-6)" << endl;
cin >> p_selection;
if (p_selection >= 1 && p_selection <= 6)
{
int i_choice = p_selection - 1;// Take one off the choice so it corresponds correctly to the object in the array
if (Weapons[i_choice].owned == false && p_balance >= Weapons[p_selection].price)// check if item is owned/can be bought
{
if (hasWeapon == false)// flip "Slot" flag
{
hasWeapon = true;
}
Weapons[i_choice].owned = true;// flip ownership flag
p_balance = p_balance - Weapons[i_choice].price; // update balance
cout << "Good eye, that's a fine item! Enjoy your " << Weapons[i_choice].name << endl;
}
else if (Weapons[i_choice].price > p_balance)
{
cout << "Seems you're a little short on gold..." << endl;
}
else if (Weapons[i_choice].owned == true)
{
cout << "Seems you don't know how to dual wield, why don't you pick something else." << endl;
}
}
}
// Check Balance
if (p_choice == 2)
{
cout << "Your balance is: " << p_balance << "g." << endl;
}
// Leave
if (p_choice == 3 && inStore == true)
{
cout << "Thanks for stopping by! Good luck out there!" << endl;
inStore = false;
}
else if (p_choice == 3 && hasWeapon == false)
{
cout << "You're gonna want a weapon out there, traveller" << endl;
}
} while (inStore == true);
//Scenario
bool scenario = true;
cout << "Inventory" << endl;
for (int x = 0; x < 6; x++)
{
if (Weapons[x].owned == true)
{
//convey slot
cout << "Press " << Weapons[x].slot << " to use your " << Weapons[x].name << endl;
cin >> p_choice;
}
}
do
{
for (int y = 0; y < 1; y++)
{
int use = p_choice - 1;
if (Weapons[use].owned == true)
{
cout << Weapons[use].sound << endl;
}
}
} while (scenario == true);
system("pause");
return 0;
}
Only issue is it plays the "sound" nonstop, that for loop was an attempt to have it run 1 time lol
