这是源程序：
// Fig. 6.10: fig06_lO.cpp
//#include <iostream.h>
// Demonstrating the Time class set and get functions
#include<iostream.h>
#include "time3.h"

void incrementMinutes(Time &, const int );

int main()
{
Time t;

t.setHour(17);
t.setMinute(34);
t.setSecond(25);

cout<<"Result of setting all valid values:\n"
<<"Hour: "<< t.getHour()
<< " Minute: " << t.getMinute()
<<" Second: "<< t.getSecond();

t.setHour( 234 ); // invalid hour set to 0
t.setMinute( 43 );
t.setSecond( 6373 ); // invalid second set to 0

cout <<"\n\nResult of attempting to set invalid hour and"
<<"second:"<<"Hour: "<< t.getHour()
<<" Minute: "<< t.getMinute()
<<" Second: "<< t.getSecond() << "\n\n";

t.setTime( 11, 58, 0 );
incrementMinutes( t, 3 );

return 0;
}

void incrementMinutes(Time &tt, const int count)
{
cout<<"Incrementing minute" << count
<< "times:\nStart time: ";
tt.printStandard();

for (int i = 0; i < count; i++ ) {
tt.setMinute( (tt.getMinute() + 1 ) % 60);

if (tt.getMinute() == 0 )
tt.setHour( ( tt.getHour() + 1 ) % 24);

cout << "\nminute + 1: ";
tt.printStandard();
}

cout << endl;
}
