Explanation / Answer
Hi,
void ConstructDate(DATE *date); // Constructor
void DestructDate(DATE *date); // Destructor
void InputDate(DATE *date); // Member function
void OutputDate(const DATE *date); //Member function
void SetDateMM(DATE *date,int MM); // MUTATOR method
void SetDateDD(DATE *date,int DD); // MUTATOR method
void SetDateYYYY(DATE *date,int YYYY); // MUTATOR method
int GetDateMM(const DATE *date); //ACCESSOR method
int GetDateDD(const DATE *date); //ACCESSOR method
int GetDateYYYY(const DATE *date); //ACCESSOR method
