Question { 52721 }

c++ program to add 2 complex number using operator
overloading technique

Answer

Write a C++ program to create a class called COMPLEX and
implement the following overloading functions ADD that
return a COMPLEX number .
I. ADD(a,s2) - where a is an integer(real part) and s2 is a
complex number.
II. ADD(s1,s2) - where s1 and s2 are complex objects.


#include
#include
class complex
{
int r,i;
public:
void read();
void print();
friend complex add(int a,complex c);
friend complex add(complex c1,complex c2);
};
void complex::read()
{
cout<<"Enter real and imaginary\n";
cin>>r>>i;
}
void complex::print()
{
cout< }
complex add(int a,complex c)
{
complex t;
t.r=a+c.r;
t.i=c.i;
return t;
}
complex add(complex c1,complex c2)
{
complex t;
t.r=c1.r+c2.r;
t.i=c1.i+c2.i;
return t;

}
void main()
{
int a=2;
clrscr();
complex s1,s2,s3;
s1.read();
cout<<"\ns1 : ";
s1.print();
s2=add(a,s1);
cout<<"s2 : 2+s1\n";
cout<<" : ";
s2.print();
s3=add(s1,s2);
cout<<"s3=s1+s2\n";
cout<<"s1 : ";
s1.print();
cout<<"s2 : ";
s2.print();
cout<<"s3 : ";
s3.print();
getch();
}

Question { IBM, 23325 }

1.program to add any two objects using operator overloading
2.program to add any two objects using constructors
3.program to add any two objects using binary operator
4.program to add any two objects using unary operator

Answer

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
#include
#include
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-> "< cout<<":"< cout<<":"< }
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();
}
