take following class and two object definitions: [CODE=c++] class Rect{ public: enum centimeter; enum meter; Rect(double len,double wid,enum centimeter){ length=(len/100); width=(wid/100); } Rect(int len,int wid,enum meter){ length=len; width=wid; } //rest of implementation private: double length;//in meters double width;//in meters }; Rect obj1(10,5,Rect::centimeter()); Rect obj2(10,5,Rect::meter());[/CODE] two previous constructors have dummy enum …

take two following classes: [CODE=c++] class Test1{ public: Test1()=default; Test1(char in1,char in2):char1(in1),char2(in2){} char char1; char char2; }; class Test2{ public: Test2()=default; Test2(char in1,char in2):char1(in1),char2(in2){} private: char char1; char char2; };[/CODE] I know in c++0x both of these classes are considered as POD types and we can initialize objects of them …
