How do I create an array of pointers

0 votes

I'm attempting to build a pointer array. These points will go to a thing I made for students. 

What should I do? What I now have is:

Student * db = new Student[5];

The student object, not a pointer to the student object, is represented by each entry in the array. 

Thanks.

Student** db = new Student*[5];
// To allocate it statically:
Student* db[5];
