a vector of references

[SECMoG1T]

Hi , I got a question about vectors, is it possible to have a vector of references to objects

  #include <vector>

  struct obj
  {
    obj(int dt): data(dt) {}
    int data;
  };
   
  int main ()
  {
   vector<obj&> vec{1, 2, 3, 4, 5, 6, 7}//is these possible? 
  
  }
 

I can't get this working

No.

Vectors contain objects. (An object is a region of storage that has a size, a type, and a lifetime.)
References are not objects. (A reference has no address of its own; it may not occupy any storage at all.)

std::reference_wrapper is a class template that wraps a reference in a copyable, assignable object. It is frequently used as a mechanism to store references inside standard containers (like std::vector) which cannot normally hold references.

There is an example at the bottom of the page.

Thanks you very much , I used the reference::wrapper n it's workin' great, I din't know vectors couldn't work with references, thank you @JLBorges
