What is the symptom of it not working?

Does it throw and exception or errors in compiling the code? If so please post those error messages.

If what you mean by the code is not working, was that the code didn't do what you expect please let us know what you expected and what the actual result was.

In short please be more specific with your questions as our time is limited and we may not ever get to helping you as that may or may not require more work then we want to do.

Please make sure that you look at the following post:

I hope I can help you further.

The code shows errors under:

1
2
3
 
Complex <int, int> x(1, 2);
	Complex <int, int> y(2, 3);
	Complex <int, int> z, w, v;

and
1
2
3
 
Complex <float, float> x2(1.3, 2.3);
	Complex <float, float> y2(2.4, 3.4);
	Complex <float, float> z2, w2, v2;


it's suppose to calculate the values of x,y,z,x1,y1,z1 but it wont run, and it says "no operators match ==" and "no operator matches <<"
i think there is somthing wrong with overloading these too operators but i dont know what's wrong.
it should also compare z with with w and cout if they have the same results or not

what's it supposed to do?

Make sure you pass the right number of template arguments.
