need it in an hour!!!!!!!!!!!!!!

The Class RingTone represents a downloadable sound that plays typically on cell phones or computers. Consider the following diagram. The instance shown on the left were created by saying:

// A RingTone that sounds like a bell and // lasts for 2 seconds RingTone rt( "bell", 2 );

Ringtone objects have the members: my_Kind( a string that describes the sound of this ringtone ) my_Length ( an int that is t he elapsed time in seconds of this ringtone when played ) For the constructors shown above, here is the class definition (.h)

Class Diagram	Class Definition (.h file)
RingTone RingTone( std::string kind, int length ); int getLength() const; std::string getKind() const; void play(); int my_Length; string my_Kind;	class RingTone { public: RingTone( std::string kind, int length ); int getLength() const; std::string getKind() const; void play(); private: int my_Length; // the length of this tone when // played std::string my_Kind; // what does this tone sound // like??? };

Based on the information shown here, a possible implementation (.cpp) for RingTone is shown below.

RingTone::RingTone( std::string kind, int length ) : my_Kind( kind ), my_Length( length ) { // EMPTY } int RingTone::getLength() const { return( my_Length ); } std::string RingTone::getKind() const { return( my_Kind ); } void RingTone::play() { cout

Based on this implementation of RingTone, define and implement the class Cellphone (a .h file and a .cpp file). A Cellphone instance represents a portable telephone that uses a ringtone. The relationship between Cellphone and RingTone is shown in the class diagram below. Make sure your definition of Cellphone supports the following kinds of constructors:

// a Cellphone with a "gong" ringtone that // lasts for 5 seconds Cellphone gongPhone; // a Cellphone with a "piano" ringtone that // lasts for 2 seconds Cellphone c( "piano", 2 );

In addition, make the operation on Cellphone defined as:

void Cellphone::receiveCall();

This operation should correctly ring the phone's RingTone.
