sorry to give you a hard time buddy. i changed you switch(choice) around --you don't need the dowhile() in there. try emulating it and tell me what happens.
Code:
switch (choice)
{
case 1:
cout << "Calculate Average Velocity" << endl;
cout << "Starting Mile Marker: " << endl;
cin >> start;
cout << "Ending Mile Marker: " << endl;
cin >> ending;
cout << "Elapsed Time: " << endl;
cout << " Hours: " << endl;
cin >> hours;
cout << " Minutes: " << endl;
cin >> min;
cout << "Seconds: " << endl;
cin >> sec;
break;
case 2:
cout << "Calculate Area of a Cirlce" << endl;
cout << "The area of a circle with radius "
<< "is " << "units." << endl;
}
how old are you, if you don't mind me asking?
