The definitions of the template should be in the headline files. Look, in the compilation.
MassClass.cppI don't know how the compilator knows.that you will install a class with a typeint? He doesn't know, and he doesn't do anything. A in the compilationSource.cppHe knows, but he can't do anything because he doesn't have a code.That's it. ♪ ♪
P.S. By the way, you've got a lot of mistakes.
MassClass.cppBut since the compiler doesn't install anything, he just doesn't notice them. ♪ ♪
