    }

    outputFile << setprecision(2) << "Grand Total" << endl << grandTotal;
    inputFile.close();
    outputFile.close();

}

Here is my code, I've been working on it for about 10 hours straight and haven't gotten any sleep and its due in about 3 hours. I'm starting to blank and I was wondering if anyone could possible help me write a code to find a grandTotal that equals the totalItemCost and the totalPotentialProfit for all items in the list. Thanks for any help!

well what have you tried already and where is it going wrong?

well its going wrong in two places it prints a subtotal after the first department and works fine from there

Code:

 if (strcmp(departmentCode, prevdept)!=0)// && strcmp(prevdept, "WHY WON'T YOU WORK??????????????")==1)
        {
            outputFile <<endl << "Department subtotal" << endl << subtotal <<endl;
            strcpy(prevdept, departmentCode);

and i tried using to variables lets just say x and y and += both with the totalItemCost and totalPotentialProfit and it gives me a negative answer in the end.

i am trying to look and see whats going on... but one thing is this??

Code:

char prevdept[7];
    strcpy(prevdept,"WHY WON'T YOU WORK??????????????");

prevdept only has 7 character space.
