help on final project

[Kingv]

I'm writing a fantasy store to purchase items from and need help passing the arrays, I know I need a switch statement; but I just kind of hit a snag and could use some help on me code.

#include <iostream>
#include <string>
using namespace std;


class Item
{
public: int cost;
public: string name;
public: string description;

// constructor
public: Item (int cost, string name, string description)
{
cost = cost;
name = name;
description = description;
}
}
}

int main (void)
{
int choice =0;
int num =0;
Item object[100];

object[0] : new Item(10, "Acid flask", "A flask filled with acid to use situationally.");
object[1] : new Item(15, "Alchemist fire", "A flask filled with a combustable gel.");
object[2] : new Item(10, "Bottled Torch", "A bottle filled with light.");
object[3] : new Item(5, "Bottle of cure disease", "A bottle of ground herbs to fight off diseases.");
object[4] : new Item(15, "Bottle of healing powder", "A bottle of ground herbs to heal scrapes and burns.");
object[5] : new Item(10, "Bottle of remove poison", "A bottle of ground herbs to remove poison.");
object[6] : new Item(20, "Healing potion", "A magical potion used to heal deep wounds.");
object[7] : new Item(25, "Potion of swiftness", "A magical potion which increases ones speed temporarily.");
object[8] : new Item(50, "Potion of true ressurection", "A magical potion which has the power to bring back to recently deceased.");

int inventory [100];
int invTot;

cout << "Welcome to the potion shop. We currently are limited on our inventory please pick from our reserves." << endl;
cout << "This is what we currently have." << endl;


for (i = 0; i < invTot; i++) {
cout << "You are carrying " << object[inventory[i]].name;
}

cout << object[i].description << " costs " << object[i].cost;

First off, put your code in between [...] and [/...] where ... is the word "code"

Name the parameter in the Item constructor different names the class variables such that you would have cost = _cost; for example.

Use = not : when assigning values to the array.

New is used when creating pointers, get rid of it or declare Item* object[100]; and don't forget to delete the pointers (I.e. every new should have a corresponding delete.)

The end of the Item class declaration should have a semicolon after the last curly brace.

invTot is uninitialized as written so using it in the loop will almost certainly cause a seg fault bc it will likely be a random large number. I would set it to 8 based on the code above.

You don't have to declare everything public individually. Write it once and then everything after it is public until you declare private or protected.
