C++ String Problem

Write a program that allows the user to enter a part number that consists of four or five characters. The second and third characters represent the delivery method, as follows: “MS” represents “Mail—Standard”, “MP” represents “Mail – Priority”, “FS” represents “FedEx – Standard”, “FO” represents “FedEx – Overnight”, and “UP” represents “UPS”. Display an appropriate message when the part number does not contain either four or five characters. Also display an appropriate message when the second and third characters are not one of the delivery methods. If the part number is vaild, the program should display the delivery method. Use the sentinel value to end the program. Save and then run the program. Test the program using the following part numbers: 7MP6, 3fs5, 2UP7, 7mS89, 9FO8, 9fo89, 8ko89, and 1234MS

Explanation / Answer

int main()

{

//Declare variables

string partNO = "";

int character = 0;

cout << "Please enter a 4 or 5 character part #: "

      << " The 2nd and 3rd characters should contain the delivery method below: "

    << " MS=Mail-Standard, MP=Mail-Priority, FS=FedEx-Standard, FO=FedEx-Overnight, UP=UPS "

     << " (enter -1 to end program) ";

   cin >> partNO;

//Determine if part # is 4 or 5 characters

  if (partNO.length() == '4' || partNO.length() == '5')     

                {             

                //Determine if 2nd or 3rd character is letters

                if (partNO[1] == 'M' && partNO[2] == 'S')

                cout << "The delivery method is Mail-Standard. ";

                else if (partNO[1] == 'M' && partNO[2] == 'P')

                cout << "The delivery method is Mail-Priority. ";

                else if (partNO[1] == 'F' && partNO[2] == 'S')

                cout << "The delivery method is FedEx-Standard. ";

                else if (partNO[1] == 'F' && partNO[2] == 'O')

                cout << "The delivery method is FedEx-Overnight. ";

                else if (partNO[1] == 'U' && partNO[2] == 'P')

                cout << "The delivery method is UPS. ";

                else

                cout << "Error: Wrong delivery method. ";

       system("pause");

                return 0;

}
