#include "Abstraction.h"int main() {AbstractionImplement* absImp1 = new ConcreteAbstractionImplement1();Abstraction* abs1 = new DefinedAbstraction(absImp1);abs1->operation();AbstractionImplement* absImp2 = new ConcreteAbstractionImplement2();Abstraction* abs2 = new DefinedAbstraction(absImp2);abs2->operation(); return 0; }
