Help with a function.
-
Hello, I am having a problem with a function. I am trying to increment a variable (odometer) using the speed and distance traveled. Below is what I have. Any suggestions are appreciated. Thanks, Eric
void drive( int, int ); // this is in the class (header file) void Car::drive( int spd, int minutes ) //implementation file { int remainderMinutes = 0; int hours; int distance; system( "CLS" ); while( minutes > 60 ) { remainderMinutes += minutes % 60 * oneDividedBySixty; minutes += remainderMinutes; } hours = minutes * oneDividedBySixty; distance = spd * minutes; cout << "\n\n The distance is " << distance << "."; cout << "\n\n The speed is " << speed << "."; cout << "\n\n The time is " << minutes << " minutes."; } int main() { Car c; char choice; do { cout << "\n\n\n Please make a selection from the menu.\n\n"; cout << "\n Press 'D' to display the car attributes.\n"; cout << "\n Press 'R' to reset the car attributes.\n"; cout << "\n Press 'X' to exit the program.\n"; cin >> choice; choice = toupper( choice ); switch( toupper( choice ) ) { case 'D': c.printCar(); break; case 'R': c.reset(); break; case 'X': break; default: cout << "\n Unknown choice entered.\n" << " Enter a new choice.\n\n"; break; } } while ( choice != 'X' ); c.reset(); c.printCar(); //c.getSpeed(); //c.getMinutes(); c.drive( c.getSpeed(), c.getMinutes() ); //c.drive( speed, minutes ); cout << "\n\n\n "; return 0; } -

My problem is that the remainderMinutes equation is not working correctly. Thank you, Eric

How did you declare (and initialize)

OK, after tracing my code, I have fixed my previous problems (I think). As of now, my two main concerns are: 1.) Making sure I convert the ints to floats correctly (where needed). 2.) Figuring out what is going on with my destructor (this is all new to me). Every time I run the program with the destructor, I get an ENTERNAL COMPILER ERROR. I really appreciate the feedback and suggestions! Thanks, Eric Here is my program:

Thanks, EricOops, nevermind the INTERNAL COMPILER ERROR. I forgot a set of parenthesis (see http://lithiumdata.com/QandA/compileerror.htm[^]). Originally I had:
Car::~Car { cout << "\n\n The destructor has been called.\n\n"; }Here is what it needs to be:Car::~Car() { cout << "\n\n The destructor has been called.\n\n"; }Thanks, Eric
