Is there any way to make custom struct - like structure on C++?

Question

There are some structures in C++ which instances can be defined as

my_structure<type> variable;

For example, std::vector

std::vector<int> very_important_vector;

And I would like to know is there any way to make my custom structure, class, or whatever definable as shown above.

Thanks in advance for your answers.

You're probably going to want a [good book](https://stackoverflow.com/questions/388242/the-definitive-c-book-guide-and-list). — molbdnilo, Dec 06 '21 at 10:05
the question reads a bit like "Can I get a hammer?" while it is not clear what nail you want to get into which wall. Templates are much more than generic containers. — 463035818_is_not_an_ai, Dec 06 '21 at 10:28

Yes, these are called class templates. One example is given below:

template<typename T>
struct my_structure
{
    //members here
};

int main ()
{
  //now you can write 
  my_structure<int> variable;//this will instantiate my_structure<int> 
  
  my_structure<float> variable2; //this will instantiate my_structure<float>
}
