Q.6 Write a
program to perform addition of two complex numbers using constructor
overloading. The first constructor which takes no arguments is used to create
objects which are not initialized. Second, which takes one argument is used to
initialize real and imaginary parts to equal values and third which takes two
arguments is used to initialize real and imaginary parts to two different
values.

public:

Complex(int r) // Parameterised constructor

}
Complex(int r,int i) // Parameterised constructor for
different values.
{
real=r;
imag=i;
}

imag=c.imag;
}
void print()
{

nos. is

{
Complex obj3;
obj3.real=obj1.real+obj2.real;
obj3.imag=obj1.imag+obj2.imag;
return obj3;
}
void main()
{
clrscr();
int a,b,c;
Complex c1; //Calling default
constructor.
cout<<"\n\t\tPROGAM TO PERFORM
ADDITION OF TWO COMPLEX NUMBERS USING CONSTRUCTOR OVERLOADING\t\t\n";
cout<<"\n\t\tFor equal values

cout<<"\n\tEnter the equal value of
real and imaginary part of number 1:\n\t";
cin>>a;
Complex c2(a); //Calling parameterised
constructor for equal values.
cout<<"\n\t\tFor different values
:\t";
cout<<"\n\tEnter the real and
imaginary part of number 2:\n\t";
cin>>b>>c;
Complex c3(b,c); //Calling
parameterised constructor for different values.
Complex c4=sum(c2,c3); //Calling copy constructor.
c4.print();
getch();
}
Output:
