1015: 计算时间间隔

使用C++编写程序：

题目描述

读入两个用“时:分:秒”表示的时间点，计算以秒为单位的时间间隔。

输入

输入有两行，每行是一个用“时:分:秒”表示的时间点。测试数据保证第二个时间点晚于第一个时间点。

输出

输出一个整数，表示时间间隔的秒数。

样例输入 Copy

08:00:00
09:00:00

样例输出 Copy

3600

程序代码如下：

一个类的情况代码：

#include<iostream>
#define ElemType_U unsigned
#define ElemType_C char

using namespace std;

class TimeInterval
{
public:
	TimeInterval(ElemType_U H, ElemType_U M, ElemType_U S, ElemType_U h, ElemType_U m, ElemType_U s) ;
	ElemType_U GetResult();
private:
	ElemType_U Hour_1, Minute_1, Second_1;
	ElemType_U Hour_2, Minute_2, Second_2;
};

inline TimeInterval::TimeInterval(ElemType_U H, ElemType_U M, ElemType_U S, ElemType_U h, ElemType_U m, ElemType_U s)
{
	Hour_1 = H;
	Minute_1 = M;
	Second_1 = S;
	Hour_2 = h;
	Minute_2 = m;
	Second_2 = s;
}

inline ElemType_U TimeInterval::GetResult()
{
	return (Hour_2 - Hour_1) * 3600 + (  Minute_2 - Minute_1 ) * 60 + ( Second_2 - Second_1 );
}

int main()
{
	ElemType_U H, M, S, h, m, s;
	ElemType_C C_1, C_2, c_1, c_2;
	cin >> H >> C_1 >> M >> C_2 >> S;
	cin >> h >> c_1 >> m >> c_2 >> s;
	TimeInterval Time(H, M, S, h, m, s);
	cout<<Time.GetResult();
	return 0;
}

类模板的代码：

#include<iostream>
#define ElemType_U unsigned
#define ElemType_C char

using namespace std;

template<class ElemType>
class TimeInterval
{
public:
	TimeInterval(ElemType H, ElemType M, ElemType S, ElemType h, ElemType m, ElemType s);
	ElemType_U GetResult();
private:
	ElemType Hour_1, Minute_1, Second_1;
	ElemType Hour_2, Minute_2, Second_2;
};

template<class ElemType>
inline TimeInterval<ElemType>::TimeInterval(ElemType H, ElemType M, ElemType S, ElemType h, ElemType m, ElemType s)
{
	Hour_1 = H;
	Minute_1 = M;
	Second_1 = S;
	Hour_2 = h;
	Minute_2 = m;
	Second_2 = s;
}

template<class ElemType>
inline ElemType_U TimeInterval<ElemType>::GetResult()
{
	return (Hour_2 - Hour_1) * 3600 + (Minute_2 - Minute_1) * 60 + (Second_2 - Second_1);
}

int main()
{
	ElemType_U H, M, S, h, m, s;
	ElemType_C C_1, C_2, c_1, c_2;
	cin >> H >> C_1 >> M >> C_2 >> S;
	cin >> h >> c_1 >> m >> c_2 >> s;
	TimeInterval<ElemType_U> Time(H, M, S, h, m, s);
	cout << Time.GetResult();
	return 0;
}

友元类的情况代码：

#include<iostream>
#define ElemType_U unsigned
#define ElemType_C char

using namespace std;

class TimeInterval_1
{
public:
	TimeInterval_1(ElemType_U h_1, ElemType_U m_1, ElemType_U s_1) :H_1(h_1), M_1(m_1), S_1(s_1) {};
private:
	friend class TimeInterval_2;
	ElemType_U H_1, M_1, S_1;
};

class TimeInterval_2
{
public:
	TimeInterval_2(ElemType_U h_1, ElemType_U m_1, ElemType_U s_1, ElemType_U h_2, ElemType_U m_2, ElemType_U s_2) :H_2(h_2), M_2(m_2), S_2(s_2), TimeVal_1(h_1, m_1, s_1) {};
	ElemType_U GetResult();
	TimeInterval_1 TimeVal_1;
private:
	ElemType_U H_2, M_2, S_2;
};

inline ElemType_U TimeInterval_2::GetResult()
{
	return (H_2 - TimeVal_1.H_1) * 3600 + (M_2 - TimeVal_1.M_1) * 60 + (S_2 - TimeVal_1.S_1);
}

int main()
{
	ElemType_U h_1, m_1, s_1, h_2, m_2, s_2;
	ElemType_C C_1, C_2, c_1, c_2;
	cin >> h_1 >> C_1 >> m_1 >> C_2 >> s_1;
	cin >> h_2 >> c_1 >> m_2 >> c_2 >> s_2;
	TimeInterval_2 Time(h_1, m_1, s_1, h_2, m_2, s_2);
	cout << Time.GetResult();
	return 0;
}

程序运行结果如下：
