first of all, as their names imply,

Getters are public methods used to retrieve some value from the class: either a property or a calculated value. These functions are 'const' and do not alter the property of an instance.

Setters are public methods used to directly set(may validate) the value of an instance property. They usually accept only one argument whose type matches the that of the property to be set. Return types are not needed(ie: void).

eg:

class Apple{
  string color;
  float mass;

public:
  // setters
  void setColor(string c);
  void setMass(float m);
  
  // getters
  string getColor() const;
  float getMass() const;
}
