c++ - Wrong number of template arguments error -

-

i'm new templates , trying use functions out of class adapt generic programming. wenn this:

template<int c, int d> class a{     ... }  float function(number<int c, int d> value);

it leads following error:

error: wrong number of template arguments (1, should 2) float function(number<int c, int d> value);                                ^

am missing here?

you need define template arguments on function , forward them type:

template<int c, int d> float function(number<c, d> value);
