Thread: Unexplainable program crash

Hi,

I have three files - routeData.h, routeData.cpp, and main.cpp. Everything runs fine, but when I try to add another public int variable into routeData.h and set it's value in main.cpp to use in routeData.cpp, my program crashes as soon as it starts up - I can't figure out why! I seem to be doing the same thing with a different int variable that I declared in routeData.h and initiated in main.cpp. Here is my code:

routeData.h

Code:

#ifndef ROUTE
#define ROUTE
#include <set>
#include <list>

using namespace std;

typedef set<int>		    iSet;
typedef list<int> 		    iLst;
typedef set<int>::iterator	iSetPtr;
typedef list<int>::iterator	iLstPtr;

class routeData
{
    public:
	
    	int readRouteData(istream & inSource);
    
    	int distance(int first, int second);
    
    	int distance(iLst route);
    
    	iLst bestRoute(iLst done, iSet left);

        int **myLocations;
        int totalLocations;
        int shortestDistance; // problem with this var
        iLst finalRoute;
        iLst holder;
        iSet locs;
};

#endif

routeData.cpp

Code:

#include <iostream>
#include <set>
#include <list>
#include <cstdlib>
#include <string>
#include <sstream>
#include <ctype.h>
#include "routeData.h"

using namespace std;

iLst routeData::bestRoute(iLst done, iSet left)
{
    int setSize;
    iSetPtr setIterator;
    iSetPtr tempPtr;
    iLst finalList;

    setSize = left.size();

    if(setSize == 0)
    {
        cout << "PERMUTATION SEQUENCE FINISHED.\n";
        cout << "->Distance of final permutation: ";
        cout << distance(done) << "\n\n";
        cout << "Comparison: distance of done = " << distance(done) << ", distance of shortestDistance = " << shortestDistance << "\n";
        if((distance(done) < shortestDistance) || (shortestDistance == -1))
        {
            cout << "Distance of done is < shortestDistance\n";
            shortestDistance = distance(done);
        }
        cout << "SHORTEST CURRENT DISTANCE: " << shortestDistance << "\n";
    }

            
    for(setIterator = left.begin(); setIterator != left.end(); setIterator++)
    {
        cout << "Iterator: " << *setIterator << "\n";

        iLst tempList = done;
        iSet tempSet = left;

        tempSet.erase(*setIterator);
        tempList.push_back(*setIterator);

        iLstPtr tempLstPtr;
        cout << "[ ";
        for(tempLstPtr = tempList.begin(); tempLstPtr != tempList.end(); tempLstPtr++)
        {
            cout << *tempLstPtr << " ";
        }
        cout << "]\t";

        iSetPtr tempPtr;
        cout << "[ ";
        for(tempPtr = tempSet.begin(); tempPtr != tempSet.end(); tempPtr++)
        {
            cout << *tempPtr << " ";
        }
        cout << "]\n";
        

        cout << "Size of list: " << tempList.size() << "\n";
        cout << "Size of set: " << tempSet.size() << "\n";
        cout << "Total distance of this list: " << distance(tempList) << "\n\n";
                
        bestRoute(tempList, tempSet);
            
    }
   
    
    return done;
}

main.cpp

Code:

#include <iostream>
#include <set>
#include <list>
#include <cstdlib>
#include "routeData.h"

using namespace std;

int main(int argc, char *argv[])
{
    routeData myRoute;
    int rrdResult;

    myRoute.myLocations = new int*[myRoute.totalLocations];

    for(int i = 0; i < 10; i++)
    {
        myRoute.myLocations[i] = new int[myRoute.totalLocations];
    }

    rrdResult = myRoute.readRouteData(cin);

    if(rrdResult < 0)
    {
        cerr << "Bad input on line " << rrdResult;
        exit(1);
    }

    for(int i = 1; i <= myRoute.totalLocations; i++)
    {
        if(i == 1)
        {
            myRoute.holder.push_back(i);
        }
        else
        {
            myRoute.locs.insert(i);
        }
    }

    myRoute.shortestDistance = -1;

    myRoute.finalRoute = myRoute.bestRoute(myRoute.holder, myRoute.locs);

    cout << "----------------------------------\n";
    cout << "DISTANCE OF LAST RETURNED ROUTE: ";
    cout << myRoute.distance(myRoute.finalRoute) << "\n\n";

    system("Pause");
    return 0;
}

I have no idea why this makes my program crash. All it says is:

This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information.

Any ideas?
