Program won't process completely

[jdwdrums]

Hi,
I have a program that is supposed to process dummy inventory data and print results to the screen. No matter what I try, I cant seem to get the program to process beyond a certain line. The code at that line is:
Inventory inv2(777,10,21.50); There are three different sections to display data and only the first one does. It seems that every time it gets to that line of code, it skips everything after that.
Here is the main program:

#include <cstdlib>
#include <stdio.h>
#include <iostream>
#include "Inventory.h"

using namespace std;

/*
*
*/
int main() {
// Declare an Inventory object and use the default constructor
Inventory inv;
// Display the member values
cout << "Object is initialized with values using the default constructor\n"; cout << "The values of the members --- \n";
cout << "Item number: " << inv.getItemNumber() << endl;
cout << "Quantity: " << inv.getQuantity() << endl;
cout << "Cost: " << inv.getCost() << endl;
cout << "Total cost: " << inv.getTotalCost() << endl;
// Define an Inventory object and use the overloaded constructor.
Inventory inv2(777,10,12.50);
// Display the member values.
cout << "Assign values to the object members using the overloaded constructor\n"; cout << "The values of the members --- \n";
cout << "Item number: " << inv2.getItemNumber() << endl;
cout << "Quantity: " << inv2.getQuantity() << endl;
cout << "Cost: " << inv2.getCost() << endl;
cout << "Total cost: " << inv2.getTotalCost() << endl << endl;
// Use the mutator functions to change the member values.
inv2.setItemNumber(555);
inv2.setQuantity(20);
inv2.setCost(19.95);
inv2.setTotalCost();
// Display the modified values.
cout << "The values are changed using mutators.\n"; cout << "The values of the members --- \n";
cout << "Item number: " << inv2.getItemNumber() << endl; cout << "Quantity: "<< inv2.getQuantity() << endl;
cout << "Cost: " << inv2.getCost()<< endl;
cout << "Total cost: " << inv2.getTotalCost() << endl << endl;
system("pause");
return 0;
}



Here is the header file:

#ifndef INVENTORY_H
#define INVENTORY_H

class Inventory {

private:
int itemNumber;
int quantity;
double cost;
double totalCost;

public:
Inventory(); //Default constructor
Inventory(int,int,double); //Second constructor
void setItemNumber(int);
void setQuantity(int);
void setCost(double);
void setTotalCost();
int getItemNumber() const;
int getQuantity() const;
double getCost() const;
double getTotalCost() const;

};

#endif /* INVENTORY_H */


and here is the resource file:


#include "Inventory.h"
#include <iostream>
#include <cstdlib>

using namespace std;

exit(EXIT_FAILURE);

{
return cost;
}

//**************************************************************************************

//**************************************************************************************

double Inventory::getTotalCost() const

}


Any assistance would be greatly appreciated.. Thanks!

Curly braces are your friends - ALWAYS use curly braces.

Inventory::Inventory(int inum, int qty, double cst )
{
    if (inum >= 0)
        itemNumber = inum;
    else
        cout << "Invalid item number! Number must NOT be less than zero.";
    exit(EXIT_FAILURE); //will always run, program ends here

    if (qty >=0)
        quantity = qty;
    else
        cout << "Invalid quantity! Number must NOT be less than zero.";
    exit(EXIT_FAILURE);

    if (cst >= 0)
        cost = cst;
    else
        cout << "Invalid cost! Number must NOT be less than zero.";
    exit(EXIT_FAILURE); 

    setTotalCost();
}

Thank you! I was just logging on to say I figured it out. Curly braces are indeed my friends!

Thanks again.
