這星期四要繳交,但我都看不懂要加入那些指令才能夠讓這段程式完整的執行出來
麻煩各位大大幫忙一下小的了
題目意思是說要寫出一個顯示時間24小時制的程式來,下面的圖片有說
要能夠順利的通過進位問題,如23:59:59 進位後變成00:00:00,這個問題比較麻煩,再來就是12:01:59
進位變成12:02:00 ,在圖片中的秒(tick)缺少了指令要我們自己加入
及這段程式碼缺主要的main funcion 來整合
語法:
// Fig. 6.19: time3.cpp
// Member-function definitions for Time class.
#include <iostream>
using std::cout;
#include <iomanip>
using std::setfill;
using std::setw;
// include definition of class Time from time3.h
#include "time3.h"
// constructor function to initialize private data;
// calls member function setTime to set variables;
// 預設 values are 0 (see class definition)
Time::Time( int hr, int min, int sec )
{
setTime( hr, min, sec );
} // end Time constructor
// set hour, minute and second values
void Time::setTime( int h, int m, int s )
{
setHour( h );
setMinute( m );
setSecond( s );
} // end function setTime
// set hour value
void Time::setHour( int h )
{
hour = ( h >= 0 && h < 24 ) ? h : 0;
} // end function setHour
// set minute value
void Time::setMinute( int m )
{
minute = ( m >= 0 && m < 60 ) ? m : 0;
} // end function setMinute
// set second value
void Time::setSecond( int s )
{
second = ( s >= 0 && s < 60 ) ? s : 0;
} // end function setSecond
// return hour value
int Time::getHour()
{
return hour;
} // end function getHour
// return minute value
int Time::getMinute()
{
return minute;
} // end function getMinute
// return second value
int Time::getSecond()
{
return second;
} // end function getSecond
// print Time in universal format
void Time::printUniversal()
{
cout << setfill( '0' ) << setw( 2 ) << hour << ":"
<< setw( 2 ) << minute << ":"
<< setw( 2 ) << second;
} // end function printUniversal
// print Time in standard format
void Time::printStandard()
{
cout << ( ( hour == 0 || hour == 12 ) ? 12 : hour % 12 )
<< ":" << setfill( '0' ) << setw( 2 ) << minute
<< ":" << setw( 2 ) << second
<< ( hour < 12 ? " AM" : " PM" );
} // end function printStandard
