예제

class MyClass {  public: MyClass(int one, int two); ~MyClass(); private: int one, two; friend const MyClass& operator*(const MyClass& left, const MyClass& rhs); }; inline const MyClass& operator*(const MyClass& left, const MyClass& right) { MyClass *result = new MyClass(left.one * right.one, left.two * right.two); return *result; }

솔루션

new로 작성된 오브젝트는 절대 리턴하지 마십시오. class MyClass {  public: MyClass(int one, int two); ~MyClass(); private: int one, two; friend const MyClass operator*(const MyClass& left, const MyClass& rhs); }; inline const MyClass operator*(const MyClass& left, const MyClass& right) { return MyClass(left.one * right.one, left.two * right.two); }
