P********e 发帖数: 2610	2 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. rhs); 【在 g*******s 的大作中提到】 : 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:

g*******s 发帖数: 59	5 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 【在 P********e 的大作中提到】 : where did you get this code? : For templates, place all the non-inline member function definition in the .h : file.
