Simulation - Running Total

[jdwright]

I am writing a simulation program and everything works fine except the running total.

The simulation loop:

  for (int sim = 0; sim < SIMS; sim++)
    {
        int cost = 0, action = 0;
        
        while (action >= 0 && action <= 2)
        {
            step = rand() % (100 + 1);
            //cout << step << endl;
            getMove (step, rPos, cPos);
            action = island[rPos][cPos];
            //cout << action << endl;
            cost += getResult (island, rPos, cPos, action, completed, rescued);
        }
        
        totalCost += cost;
        cout << totalCost;
    }

The getResult function:

int getResult (int ary[][14], int r, int c, int action, int &complete, int &rescue)
{
    int cost = 0;
    //Fell in water. Must be rescued.
    if (action == -1)
    {
        rescue++;
    }
    
    //Made it to one of the two bridges.
    if (action == 3)
    {
        complete++;
    }
    
    //Stepped on one of two flowers in a cell. Owes $5.
    if (action == 2)
    {
        cost = 5;
        ary[r][c]--;
    }
    
    //Stepped on the last flower in a cell. Owes $5.
    if (action == 1)
    {
        cost = 5;
        ary[r][c]--;
    }
    
    return cost;
}

When I print out totalCost I get something like:

9595959510010010010010012512512
5125125125125125125125125125125
1251251251251251251251251251251
2512512512512512512512512512512
5125125125125125125125125125125
1251251251251251251351351351351
3513513513513513513513513513513
5135135135145145145145145145145
1451451451451451451451451451451
5015015015015015015015015015015
0150150150150150150150150150150
1501501501501501501501501501501
5015015015015015015015015015015

I'm new to simulation and haven't found any info on what would cause this.

OK, I just realized my cout << totalCost; was in a very bad place.
