C++ Friend Classes -

-

just trying make sure have understood friends one

class {   friend class b;   int valueone;   int valuetwo;   public:   int getvalueone(){ return valueone; } } class b {   public:   friendlydata;   int getvaluetwo(){ return friendlydata.valuetwo; } } main() {   b myobject;   myobject.friendlydata.getvalueone(); // ok?   myobject.getvaluetwo(); // ok? }

in reference code about, if ignore lack of initialising, 2 functions in main ok right? , besides doing funky stuff, should no other way data these classes... out side of these class, b.a has no accessible data, member function.

yes 2 identified calls in main ok. involve access of 3 members: b::a, b::getvaluetwo , a::getvalueone. of have publicaccessibility , expose no privae types. hence they're usable anywhere including main.
