object in c++

[foozhan]

hi all
is it possible to don't declare an object for a class and use the function of this class ? i saw a code use this but i cannot find it again .. can someone tell me what is this style name?

Hello,
you can declare function to be static.

you can use a function of a class without object when you have a static function. But then you cannot use member variables of that class

but in this example in this link all of them have object in main function

No they dont have an object. they are called via the struct/class itself.

// static data members and functions belong to the class and
  // can be accessed without using an object of class X
  X::print_si();
  X::set_si(22);
  X::print_si();
