Hints

1. Bring humans to the world of Troy

The core of this exercise is the usage of unique_ptr and shared_prt. Which kind of smart pointer should be used for each of the human variables?
artifacts are not shared, but powers are needed to track influenced people.
the possession pointer should be unique, the power pointers should be shared.

2. Bring Artifacts into Troy

You need to create a smart pointer and assign it to the possession variable
Use references to change the object outside of the function.
Look up std::make_unique for some hints.
The type of the pointer's target object has to be put in the angled brackets and again inside the parens to define the object.
Here is a full example: variable = std::make_unique<int>(int{23});

3. Make items tradeable

You can look through the unique_ptr reference to find a fitting function.
Do you think std::swap can help you?

4. Give Power to the People

You need to create a smart pointer and assign it to the own_power variable
Use references to change the object outside of the function.
Look up std::make_shared for some hints.
The type of the pointer's target object has to be put in the angled brackets and again inside the parens to define the object.
Here is a full example: variable = std::make_shared<int>(int{23});

5. Use the Power

Use references to change the object outside of the function.

6. Keep watch on the power's intensity

You can look through the shared_ptr reference to find a fitting function.
Do you think use_count can help you?
