you can use a pointer to a pointer; example: int x=0; int *ptr1 = &x; int **ptr2 = &ptr1; in this case ptr2 store the address of ptr1. You can also change the value of x by dereferencing twice ptr2: main() { using namespace std; int x=0; int *ptr1 = &x; int **ptr2 = &ptr1; **ptr2 = 3; cout << "value of x is: " << x; return 0; } this will print 3 as the value of x, because you changed it using ptr2
