template<>
class A<char> { // Error here
public:
A(char c)
{
// Do something here.
}
};
When I hover on A, it says "A is not a template".

2And where is the templated `A`? – Yksisarvinen Oct 26 '18 at 12:05

1A is not a template, why do you think it is? – 463035818_is_not_an_ai Oct 26 '18 at 12:05

i dont get the close reasons. How is this "too broad" ?? – 463035818_is_not_an_ai Oct 26 '18 at 12:09

Probably because you never declared a class template called "A". You can't specialise something that does not exist. – molbdnilo Oct 26 '18 at 12:10

I watched a tutorial, and tried to do exactly same thing. It doesn't work on mine. – Brian Oct 26 '18 at 12:29

1i am not going to tell you how you should learn, but be careful with online c++ tutorials, there are just too many of poor quality (once you can identify the good ones you probably dont need them anymore ;). Take a look [here](https://stackoverflow.com/questions/388242/the-definitive-c-book-guide-and-list) for books – 463035818_is_not_an_ai Oct 26 '18 at 12:34

You need to declare the template before you can specialize it:
// declare the template
template <typename T> // no need to define it
struct A; // if you only want the specialization
// declare and define the specialization
template<>
struct A<char> {};
