Pointers in C/C++• Extremely flexible but must be used with care:– Pointers can point at any variable regardless of when or where itwas allocated.– Used for dynamic storage management and addressing.– Explicit dereferencing (∗) and address-of (&) operators.– Domain type need not be fixed:• void * can point to any type and can be type checked.• void * cannot be de-referenced.– Pointer arithmetic is possible.Lecture 0642
Pointer Arithmetic in C/C++float stuff[100];float *p;p = stuff;*(p+5) is equivalent to stuff[5] and p[5]*(p+i) is equivalent to stuff[i] and p[i]Lecture 0643
