Daved, thanks for the help... unfortunetely I cannot use what you have provided me
This is homework (if you couldn't guess :P ), and we aren't allowed to use anything that hasn't been covered in class up until this point.
There's another thing that's bothering me. There is an example in the book (a gradebook) that uses an integer type, and allows for entering characters without going into a fail state... here's the code:
... I just don't get it. I ran this program and input characters that weren't allowed for in the case section (such as g and t) and it successfully defaulted...Code:void GradeBook::inputGrades() { int grade; // grade entered by user cout << "Enter the letter grades." << endl << "Enter the EOF character to end input." << endl; // loop until user types end-of-file key sequence while ( ( grade = cin.get() ) != EOF ) { // determine which grade was entered switch ( grade ) // switch statement nested in while { case 'A': // grade was uppercase A case 'a': // or lowercase a aCount++; // increment aCount break; // necessary to exit switch case 'B': // grade was uppercase B case 'b': // or lowercase b bCount++; // increment bCount break; // exit switch case 'C': // grade was uppercase C case 'c': // or lowercase c cCount++; // increment cCount break; // exit switch case 'D': // grade was uppercase D case 'd': // or lowercase d dCount++; // increment dCount break; // exit switch case 'F': // grade was uppercase F case 'f': // or lowercase f fCount++; // increment fCount break; // exit switch case '\n': // ignore newlines, case '\t': // tabs, case ' ': // and spaces in input break; // exit switch default: // catch all other characters cout << "Incorrect letter grade entered." << " Enter a new grade." << endl; break; // optional; will exit switch anyway } // end switch } // end while } // end function inputGrades
