Object Delete Operator delete

The delete operator deletes an object created by the new operator, calls the corresponding class destructor and frees up memory occupied by the object. A real descriptor of an existing object is used as an operand. After the delete operation is executed, the object descriptor becomes invalid.

      delete m_shape;
      //--- create a new figure
