When dealing with classes, when is is appropriate to use the dot operator or the scope resolution operator ?

The scope resolution operator is used to qualify hidden names so you can use them. See this link. You use the dot operator to access class member objects.

the scope resolution orperator is used to refer to members of a pointer object

[codeprada]

//Use of dot operator
AClass a; //a is an instance of class AClass
a.doSomething();

//Use of scope resolution operator
AClass * b = &a; //b is a pointer of type AClass that points to the address of a
b->doSomething();

-> is NOT the scope resolution operator. It is the "pointer to member operator" or some such clumsy name.

The scope resolution operator is the double colon :: which as jimblumberg said is used to qualify names (to make explicit the scope or namespace in which they are defined).
