使用VC6打开考生文件夹下的工程test33_3。此工程包含一个test33_3.cpp，其中定义了表示时间的类Time，但Time类定义并不完整。请按要求完成下列操作，将程序补充完整。(1)定义类Time的私有数据成员hours、minutes和seconds，它们都是int型的数据，分别表示时间的小时、分和秒。请在注释“//**1**”之后添加适当的语句。(2)完成类Time缺省构造函数的定义，该函数将数据成员hours、minutes和seconds的值初始化为0，请在注释“//** 2**”之后添加适当的语句。(3)完成类Time带参构造函数的定义，该函数将数据成员hours、minutes和seconds的值分别初始化为参数h、m和s的值，请在注释“//**3**”之后添加适当的语句。(4)完成类Time中运算符“+”的重载，注意小时、分和秒在相加时的进位问题。请在注释“//**4**”之后添加适当的语句。注意：除在指定位置添加语句之外，请不要改动程序中的其他内容。程序输出结果如下：8：17：11源程序文件test33_3.cpp清单如下：include ＜iostream.h＞class Time{//** 1 **public:Time ( ){//** 2 **seconds=0;}Time(int h, int m, int s){//** 3 **minutes=m;seconds=s;}Time operator +(Time);void gettime();};Time Time::operator +(Time time){//** 4 **s=time.seconds+seconds;m=time.minutes+minutes+s/60;h=time.hours+hours+m/60;Time result(h,m%60,s%60);return result;}void Time::gettime(){cout＜＜hours＜＜":"＜＜minutes＜＜":"＜＜seconds＜＜end1;}void main( ){Time t1(3,20,15),t2(4,56,56),t3;t3=t1+t2;t3.gettime();}
