Returning Object

I have this c++ code:

Code:

#include&ltiostream&gt
using namespace std;

class Complex{
	float real;
	float imaginary;
public:
	void getvalue(float,float);
	void putvalue();
	Complex sum(Complex,Complex);
};

void Complex::getvalue(float re,float im){
	real=re;
	imaginary=im;
}

void Complex::putvalue(){
	cout&lt&ltreal&lt&lt"+j"&lt&ltimaginary&lt&ltendl;
}

Complex Complex:: sum(Complex x,Complex y){ 
	Complex p;
	p.real=x.real+y.real;
	p.imaginary=x.imaginary+y.imaginary;

	return p;
}

int main(){
	Complex x,y,z;
	x.getvalue(2,8);
	y.getvalue(4,9);
	z=sum(x,y);
	z.putvalue();

	return 0;
}

I want to return p from 'sum' method.But the compiler shows error.Please suggest.

I think you want to do

Code:

#include<iostream>
using namespace std;

class Complex{
  float real;
  float imaginary;
 public:
  void getvalue(float,float);
  void putvalue();
  static Complex sum(Complex,Complex);
};


Complex Complex::sum(Complex x,Complex y){
  Complex p;
  p.real=x.real+y.real;
  p.imaginary=x.imaginary+y.imaginary;

  return p;
}

//....

int main(){
  Complex x,y,z;
  x.getvalue(2,8);
  y.getvalue(4,9);
  z = Complex::sum(x,y);
  z.putvalue();

  return 0;
}

learning how to use pointers and templates will save you a lot of pain and suffering when it comes to problems like those.
