In session : An owning type erasure implemention
this code can not compile at this line : Shape shape( drawingCircle );
Am I need to change the implemention of Shape Class ?
//---- <YourMain.cpp> ----------------
int main()
{
// Create a circle as one representative of a concrete shape type
Circle circle{ 3.14 };
// Bind the circle to some drawing functionality
auto drawingCircle = = { myCircleDrawer(circle); };
// Type-erase the circle equipped with drawing behavior
Shape shape( drawingCircle );
// Drawing the shape
draw( shape );
// ...
return EXIT_SUCCESS;
