Please note that private constructors required to ensure uniqueness enforce. Destructors Unlike constructors, a class can have only one destructor Takes a pointer to instance and reverses actions of the constructor: a) initialize vfptrs if has virtual functions (this is done so that any virtual calls in the body use the methods of the current class) b) execute the destructor body c) call destructors of complex class members Overloading a destructor is not possible and can be explicitly invoked. . -Wglobal-constructors declaration requires a global constructor-Wglobal-constructors declaration requires a global destructor-Wgnu-conditional-omitted-operand use of GNU ?
