vector of pointers

[eliranko]

I was wondering if there is a difference between:

vector<Course*> courses;
Course* cs = new CScourse(); //CScourse inherits Course
courses.push_back(cs);

and

void something(Course& c){ //c is also located on heap
courses.push_back(&c);
}

is there a difference between pushing a pointer and pushing reference?

There is, although in both your examples above you're pushing a pointer to a Course object.

¿can you `store' references?

[vlad from moscow]

You are not pushing a reference. In the both cases you are pushing a pointer to an object of type Course I think that using CScourse() in the first example is a typo) . The difference is that in the first case we know that we are pushing a pointer that points to an object created in the heap while in the second case we can say nothing about where the object was created.

The same could be say with

void foo(Course *bar){
   courses.push_back(bar);
}
