Template<> without any content

Hello everyone,
I sometimes saw code with template<and followed by a class
definition, like,

Expand|Select|Wrap|Line Numbers
  1. template<class {
  2.  
  3. // class definition
  4. }
  5.  
I am wondering the practical usage of this trick. Why declar a
template but leaving the content to nothing? If there is no type
parameters, I do not think there is a need to put template<>
statement.
thanks in advance,
George

I think you want comp.lang.c++. C doesn't have templates or classes

Go to <news:comp.lang .c++>

'template<>' is a syntax error in C. You probably want to ask in a
newsgroup for a language in which that construct is legal.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.
