'Doubling dynamically allocated memory in a function using loops and conditions C++

So I need to add already existing films to a Listfilms function that allocates the films dynamically, and if there is no more space we have to double the allocated memory. How do I use pointers and "new" and "delete" methods in C++ please? And another - remove a film from the ListFilms without deleting it?

void ListFilms(string Films[],int nbElements, int* p){
        for (int i=0; i<nbElements;i++){
            if (Films[i]> *p){
                

                }
            }

This is basically my start but I know it is wrong. Can someone help me with this?
