Create a class called 'time' that has three integer data
members for hours, minutes and seconds, define a member
function to read the values, member operator function to add
time, member function to display time in HH:MM:SS format.
Write a main function to create two time objects, use
operator function to add them and display the results in
HH:MM:SS format.


#include<iostream.h>
#include<conio.h>
#include<iomanip.h>
class time
{
int h,m,s;
public:
void read();
void print();
time operator+(time t2);
};
void time::read()
{
cout<<"\nEnter hour,minutes and seconds\n";
cin>>h>>m>>s;
}
void time::print()
{
cout<<"\nTime is-> "<<setfill('0')<<setw(2)<<h;
cout<<":"<<setfill('0')<<setw(2)<<m;
cout<<":"<<setfill('0')<<setw(2)<<s<<endl;
}
time time::operator+(time t2)
{
time t;
t.h=h+t2.h;
t.m=m+t2.m;
t.s=s+t2.s;
return t;
}
void main()
{
clrscr();
time t1,t2,t3;
t1.read();
t1.print();
t2.read();
t2.print();
t3=t1+t2;
cout<<"\nTime1+ Time2:\n";
t3.print();
getch();
}

What output does the following code generate? Why? What output does it generate if you make A::Foo() a pure virtual function? class A { A() { this->Foo(); } virtual void Foo() { cout << "A::Foo()" << endl; } }; class B : public A { B() { this->Foo(); } virtual void Foo() { cout << "A::Foo()" << endl; } }; int main(int, char**) { A objectA; B objectB; return 0; }
