Question

How to make_unique and return a unique_ptr.

Answer 1

Can you specify the task better please?

Answer 2

I'm not sure how the data for your shapes are supposed to be, so I just specified the Points belonging to them. The rectangle is not guaranteed to be 90 deg, so it should probably just be a considered as general quadrangle. More complicated constuctors are probably needed, but that is not the focus of this exercise.

Anyway, this is how I would do it. It might not be what you're after but perhaps it will give you some ideas.

I also added an extra experimental method to generate a random pick of shape from a single method, returning a custom type based on std::variant.

Answer 3

It says “Create a class called ShapeFactory. Add 7 static methods: a method for creating a random point, a method for creating a random color, and methods for creating unique pointers for each Shape type (Shape, Line, Rectangle, Triangle, Circle). The methods that create the random Shapes should use make_unique and return a unique_ptr.” I just need an example
