Slip 9 - B) Create a C++ class Time with data members Hours, Minutes and Seconds. Write necessary member functions for the following: (Use Objects as arguments) i. To accept a time. ii. To display a time in format hh:mm:ss. iii. To find difference between two time and display it in format hh:mm:ss.

 Solution:

#include<iostream.h>

#include<conio.h>

#include<iomanip.h>

class time

{

int h,m,s;

public:

void getdata();

void display();

time operator-(time t2);

};

void time::getdata()

{

cout<<"\nEnter hour,minutes and seconds\n";

cin>>h>>m>>s;

}

void time::display()

{

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.getdata();

t1.display();

t2.getdata();

t2.display();

t3=t1-t2;

cout<<"\nTime1 - Time2:\n";

t3.display();

getch();

}
