模板参数数量错误

Question

I'm new to templates and trying to use my functions that are out of the class to adapt to the generic programming. But wenn I do this:

template<int C, int D>
class A{
    ...
}

float function(number<int C, int D> value);

it leads to following error:

Error: wrong number of template arguments (1, should be 2)
float function(number<int C, int D> value);
                               ^

Am I missing something here?

Answer 1

You need to define template arguments on the function and forward them to the type:

template<int C, int D>
float function(number<C, D> value);
