Answer to Question #176343 in C++ for Muhammad Ahmed

Question

Write base class that ask the user to enter a complex number and derived class adds the complex number of its own with the base. Finally make third class that is friend of derived and calculate the difference of base complex number and its own complex number.

Answer 1

#include<iostream.h>
#include<conio.h>
class complex
{
   private:
	float x;
	float y;
   public:
	void set(float real, float img)
	{
		x=real; y=img;
	}
	complex sum(complex);
	void disp();
};
complex complex::sum(complex C)
{
	complex t;
	t.x = x + C.x;
	t.y = y + C.y;
	return t;
}
void complex::disp()
{
	cout<<x<<" + j"<<y<<endl;
}
int main()
{
	complex C1,C2,C3;
	C1.set(2.5,7.1);
	C2.set(4.2,5.5);
	C3=C1.sum(C2);
	cout<<"\n complex Number 1 = ";C1.disp();
	cout<<"\n complex Number 2 = ";C2.disp();
	cout<<"\n complex Number 3 = ";C3.disp();
	getch();
	return 0;
}
