Lesson 3: Classes

Activity 7: Information Hiding Through Getters and Setters

1. Define a class named Coordinates with its members under a private access specifier:

   class Coordinates {
     private:
       float latitude;
       float longitude;
   };

2. Add the four operations as specified above and make them publicly accessible by preceding their declaration with the public access specifier. The setters (set_latitude and set_longitude) should take an int as a parameter and return void, while the getters do not take any parameter and return a float:

   class Coordinates {
     private:
       float latitude;
       float longitude;
   
     public:
       void set_latitude(float value){}
       void set_longitude(float value){}
       float get_latitude(){}
       float get_longitude(){}
   };

3. The four methods should now be implemented. The setters assign the given value to the corresponding members they are supposed to set; the getters return the values that are stored.

   class Coordinates {
     private:
       float latitude;
       float longitude;
   ...
