Three files:
complex.h
#ifndef COMPLEX_H
#define COMPLEX_H
#include
using namespace std;
template
class Complex{
friend ostream & operator << (ostream &output, const Complex &rhs);
private:
T real;
T imaginary;

public:
explicit Complex(T x, T y):real(x),imaginary(y){}
~Complex(){}
Complex & operator +(const Complex &rhs) const;
.
.
.
};
#endif
complex.cpp
#include "complex.h"
using namespace std;
template
ostream & operator

where did you get this code?
For templates, place all the non-inline member function definition in the .h
file. This seems contrary to ordinary, but for templates, those member
function will not be compiled and will be waiting for run-time type define.
I don't know if this will help, but at least, you can get something right.

"run-time type define"...
i don't think C++ provides this

.h

3x. i write these codes myself.
I was thinking to write them in a .cpp as usual but i fail
to know template function would be better put inside one .h file.

.h
