Arrays, parameter passing, pointers and dynamic allocation. - ELIS

S Differences
Pointers vs. References
S In reference declaration (int &cRef = count;), “&” is part of type,
it is not an operation (as with pointers)
S References have to be initialized at declaration time
S void func_ptr(int *pi) {*pi = 5;}
S void func_ref(int &ri) {ri = 6;}
S int num; int *p = # int &r = num;
S func_ptr(&num);
S func_ref(num); //We are passing parameters by… what?
