OOP Time Clock Parametrized and Default Constructor
Task To Convert Twenty Four Hour Format To Twelve Hour Format
Complete the function definitions of the following ADT
class Time
{
public:
void setTime( int, int, int ); // set hour, minute, second
void setHour( int ); // set hour
void setMinute( int ); // set minute
void setSecond( int ); // set second
int getHour(); // return hour
int getMinute(); // return minute
int getSecond(); // return second
void printTwentyFourHourFormat(); // print universal time
void printTwelveHourFormat(); // print standard time
private:
int hour; // 0 - 23 (24-hour clock format)
int minute; // 0 - 59
int second; // 0 - 59
};
