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();
}

Write a C++ program without using any loop (if, for, while etc) to print prime numbers from 1 to 100 and 100 to 1 (Do not use 200 print statements!!!)
Write a program using one dimensional array that accept five values from the keyboard. Then it should also accept a number to search. This number is to be searched if it among the five input values. If it is found, display the message “Search number is found!” otherwise, display “Search is lost”. Example: Enter 5 numbers: 10 15 20 7 8 Enter number to search: 7 Search number is found!

what mean void creat_object?in public class in this code class A{ public: int x; A(){ cout << endl<< "Constructor A";} ~A(){ cout << endl<< "Destructor A, x is\t"<< x;} }; void create_object(); void main() { A a; a.x=10; { A c; c.x=20; } create_object(); } void create_object() { A b; b.x=30; }

write a c program, using for loop, that accepts and odds two numbers. The output must be the sum and the addens. This should be repeated 5 times while the first number is decremented by one and the second number is incremented by 1.
main(){int a=5,b 10,c=2, d;a=b c;d=++a=(--c)*2; printf("%d%d%d%d,a,b,c,d; return o;}

Subsets Write an algorithm that prints out all the subsets of 3 elements of a set of n elements. The elements of the set are stored in a list that is the input to the algorithm. (Since it is a set, you may assume all elements in the list are distinct.)

What output does this program generate as shown? Why? class A { A() { cout << "A::A()" << endl; } ~A() { cout << "A::~A()" << endl; throw "A::exception"; } }; class B { B() { cout << "B::B()" << endl; throw "B::exception"; } ~B() { cout << "B::~B()"; } }; int main(int, char**) { try { cout << "Entering try...catch block" << endl; A objectA; B objectB; cout << "Exiting try...catch block" << endl; } catch (char* ex) { cout << ex << endl; } return 0; }

write a function -oriented program that generates the Fibonacci, the current numbers of n(as input) and display them (series). In Fibonacci, the current third number is the sum of the previous number.
