Answer to Question #183032 in C++ for Vincenzo Santoro

Question

This chapter defines the class clockType to implement time in a program. Add functions to this class so that a program that uses this class can set only the hours, minutes, or seconds and retrieve only the hours, minutes, or seconds. Make the functions that retrieve hours, minutes, and seconds as inline. Also, write a program to test your class.

The header file for the class clockType, as it is defined in this chapter, has been provided for you.

Answer 1

#include <iostream>
class clockType
{
public:
	void set_hour(int h);
	int get_hour();
	void set_minut(int m);
	int get_minut();
	void set_second(int s);
	int get_second();
	clockType() {};
	clockType(int h,int m,int s) 
	{
		h = ((h < 0) ? 0 : (h > 23) ? 23 : h);
		m = ((m < 0) ? 0 : ( m> 59) ? 59 : m);
		s = ((s< 0) ? 0 : (s > 59) ? 59 : s);
		hour = h;
		minut = m;
		second = s;
	}
private:
	int hour{ 0 };
	int minut{ 0 };
	int second{ 0 };
};


inline void clockType::set_hour(int h) 
{
	h = ((h < 0) ? 0 : (h > 23) ? 23 : h);
	hour = h;
}
inline void clockType::set_minut(int m)
{
	m = ((m < 0) ? 0 : (m > 59) ? 59 : m);
	minut = m;
}
inline void clockType::set_second(int s)
{
	s = ((s < 0) ? 0 : (s > 59) ? 59 : s);
	second = s;
}
inline int clockType::get_minut() 
{
	return minut;
}
inline int clockType::get_second()
{
	return second;
}
inline int clockType::get_hour()
{
	return hour;
}


int main()
{
	// example test program
	// set time 22:54:12
	clockType test(22, 54, 12);
	std::cout << "Set time :" << test.get_hour() << "h" << test.get_minut() << "m" << test.get_second() << "s" << std::endl;
	// set time 18:18:54
	test.set_hour(18);
	test.set_minut(18);
	test.set_second(54);
	std::cout << "Set time :" << test.get_hour() << "h" << test.get_minut() << "m" << test.get_second() << "s" << std::endl;
	system("pause");
	return 0;
