Info

Pointer Operators S * in indirection or dereferencing operator. S Pointer is undefined when created – can be set to 0 or NULL S Dereferencing an uninitialized or NULL pointer is BAD! S What if we did (*count)? S Or int *countPtr; then (*countPtr) ? 54 7 count
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 = &num; int &r = num; S func_ptr(&num); S func_ref(num); //We are passing parameters by… what? 55
