When to use . operator and when to use -> operator ?

Question

. is direct access operator
-> is indirect access operator
Can anyone explain , please?

Answer 1

The target. dot works on objects; arrow works on pointers to objects.

std::string str("foo"); std::string * pstr = new std::string("foo"); str.size (); pstr->size ();
The . operator is for direct member access.

object.Field

The arrow dereferences a pointer so you can access the object/memory it is pointing to

pClass->Field
