|
| • | We
begin with the keyword template followed by the |
||||||||
| template's
formal argument list inside of angle brackets (< |
|||||||||
| >). |
|||||||||
| • | This
is followed by the function's header (i.e., the |
||||||||
| function's
return type, name, and argument list). |
|||||||||
| • | The
signature of a function template is the function's |
||||||||
| signature,
its return type, along with the template's formal |
|||||||||
| argument
list. |
