// Change.h class Change { private: int numTwenties; int numTens; int numFives; int numOnes; int numQuarters; int numDimes; int numNickels; int numPennies; public: Change(); Change( double dollars ); Change( int twenties, int tens, int fives, int ones, int quarters, int dimes, int nickels, int pennies ); double AmountInDollars(); void SetAmount( double dollars ); // I would probably add a method for setting/getting each of the twenties/tens/etc. void SetTwenties( int twenties ); int GetTwenties(); }; CPP / C++ / C Code: // Change.cpp // Default constructor Change::Change() { SetAmount( 0.00 ); } Change::Change( double dollars ) { SetAmount( dollars ); } void SetAmount( double dollars ) { numTwenties = 0; numTens = 0; numFives = 0; numOnes = 0; numQuarters = 0; numDimes = 0; numNickels = 0; numPennies = 0; while( dollars >= 20.00 ) { numTwenties++; dollars -= 20.00; } while( dollars >= 10.00 ) { numTens++; dollars -= 10.00; } while( dollars >= 5.00 ) { numFives++; dollars -= 5.00; } while( dollars >= 1.00 ) { numOnes++; dollars -= 1.00; } while( dollars >= 0.25 ) { numQuarters++; dollars -= 0.25; } while( dollars >= 0.10 ) { numDimes++; dollars -= 0.10; } while( dollars >= 0.05 ) { numNickels++; dollars -= 0.05; } while( dollars >= 0.01 ) { numPennies++; dollars -= 0.01; } } double AmountInDollars() { return 20.0*numTwenties + 10.0*numTens + 5.0*numFives + numOnes + 0.25*numQuarters + 0.1*numDimes + 0.05*numNickels + 0.01*numPennies; }
