    Visual Studio Just-In-Time Debugger Error

    Hello everybody I'm in the middle of programming a basic console application that is supposed to be a stock market game for my programming class in c++. I have run into this weird error involving a Visual Studio Just-In-Time Debugger window popping up saying I have a Win 32 unhandled exception even though I am using Code::Blocks 10.05 as my IDE, not Visual C++.

    Now my whole project is rather long(at least from my point of view) so far but basically what happens is that I have a main function, a class named CStock(which is what the stocks in my game are made from) and then a bunch of other functions that make up different parts of the program (generating a random number, publishing the prices to the console, and some others).

    I had started out declaring the different stocks after the Class using their names (Gold, Silver, Beef, etc), but then I wanted to declare them as an array instead so that it would be easier to add or change the amount of stocks I had in the game.

    Once I changed to declaring the stocks after the class as an array, however, I got the error. I do not receive the error if I declare the array of stocks during a seperate function (not directly after the class), but then I cannot access the array of stocks in all the functions of my program.

    Here Is my code so far and I would greatly appreciate any help/ advice anyone has to offer.

    Code:
    //This class creates a stock with the initial name and value inputted
    class CStock
    {
            public:
                int iPrice, iTrend, iChange, iAmountOwned;
                string sStockName;
                CStock();                      //constructor
    
                void ChangePrice()
                //changes this stock's price
                {
                    int iRanNum;
                    iRanNum = RandomNumber(-50, 50);
                    //iRanNum = (rand() % 101) - 50;
                    iPrice+=iRanNum;
                    iChange=iRanNum;
                    iTrend+=iRanNum;
                };
    
                void PublishPrice()
                //publishes the current info for this stock
                {
                    cout<<sStockName<<" Price: "<<iPrice<<" Change: "<<iChange<<" Trend: "<<iTrend<<endl;
                };
    
                void Buy(int iAmountToBuy)
                //Buys an amount of stocks for the user
                {
                    int iTotalCost;
                    //calculates total price
                    iTotalCost=iAmountToBuy*iPrice;
                    //only buys the stocks if you have enough money too
                    if(iUserMoney>=iTotalCost)
                    {
                    iUserMoney=iUserMoney-iTotalCost;
                    iAmountOwned+=iAmountToBuy;
                    cout<<endl<<"Money: "<<iUserMoney<<" "<<sStockName<<" Owned: "<<iAmountOwned<<endl;
                    }
                    else{cout<<endl<<"Get more money you hobo!"<<endl;};
                };
    
                void Sell(int iAmountToSell)
                //Sells an amount of stocks for the user
                {   //only sells if you input a valid amount to sell

                    {

                        //calculates how much money you will earn and adds it to user's total money
                        iMoneyEarned=iAmountToSell*iPrice;
                        //as well as subtracting the amount of stocks that were sold
                        iAmountOwned-=iAmountToSell;
                        iUserMoney+=iMoneyEarned;
                        cout<<endl<<"Money: "<<iUserMoney<<" "<<sStockName<<" Owned: "<<iAmountOwned<<endl;
                    }
                    else{cout<<endl<<"You cannot sell that many!"<<endl;}   //outputs this message if an invalid amount is tried to be sold
    
                }

    It means that you have Visual Studio installed and it is set to catch errors that occurs (instead of the "this program has done something illegal and needs to be closed") and offers to launch a debugger to see where the error lies.
    In other words, your program crashed.

    So I suggest you open up C::B and launch it in a debugger or using Visual Studio to find out where the error occurs. Then backtrace to find the problem.

    Outside of your DOS world, your header file is meaningless.
