1.1编写一种基于对象的程序，规定：（1）定义一种时间类Time，类内有私有数据组员hour（小时）、minute（分钟）、sec（秒），公有组员函数set_time()、show_time()。（2）set_time()函数和show_time()函数在类内定义。set_time()作用是从键盘输入时间、分钟、秒的值，show_time()的作用是在屏幕上显示时间、分钟、秒的值。（3）在main()函数定义Time类的对象t1，并调用set_time()函数给时间赋值，调用show_time()函数输出时间的值。#includeusingnamespacestd;classTime{public:voidset_time(){cin>>hour;cin>>minute;cin>>sec;}voidshow_time(){cout<usingnamespacestd;classBox{public:voidget_value();voidvolume();private:floatlengh;floatwidth;floatheight;};voidBox::get_value(){cout<<"pleaseinputlengh,width,height:";cin>>lengh;cin>>width;cin>>height;}voidBox::volume(){cout<<"volmueofbox1is"<usingnamespacestd;classArray_max{public:voidset_value();voidmax_value();private:intarray[10];intmax;};voidArray_max::set_value(){inti;for(i=0;i<10;i++)cin>>array[i];}voidArray_max::max_value(){inti;max=array[0];for(i=1;i<10;i++)if(array[i]>max)max=array[i];cout<<"max="<usingnamespacestd;classComplex{public:Complex(){real=0;imag=0;}Complex(doubler,doublei){real=r;imag=i;}Complexoperator+(Complex&c2);voiddisplay();private:doublereal;doubleimag;};ComplexComplex::operator+(Complex&c2){Complexc;c.real=real+c2.real;c.imag=imag+c2.imag;returnc;}voidComplex::display(){cout<<"("<classComplex{public:Complex(){real=0;imag=0;}Complex(doubler){real=r;imag=0;}Complex(doubler,doublei){real=r;imag=i;}friendComplexoperator+(Complex&c1,Complex&c2);voiddisplay();private:doublereal;doubleimag;};Complexoperator+(Complex&c1,Complex&c2){returnComplex(c1.real+c2.real,c1.imag+c2.imag);}voidComplex::display(){cout<<"("<
