 ### Solution
 
 See [slide11.cpp](./slide11.cpp).
+
+## Slide 13
+
+### Problem
+
+```cpp
+class Human
+{
+public:
+    Human();
+    ~Human();
+private:
+    std::string name;
+    int age;
+};
+```
+
+Try this:
+
+1. Try to retrieve the data from all humans and print it to the screen.
+2. Try to find a workaround for the errors (if you don’t see any errors you’re doing something wrong).
+
+### Solution
+
+1. Because the `name` and `age` fields are private, they cannot be accessed.
+2. A solution would be creating getters for them:
+
+```cpp
+class Human
+{
+    ...
+public:
+    const std::string& getName();
+    const int& getAge();
+};
+```
