class Person { private: string name; int age; public: void setName(string n) { name = n; } void setAge(int a) { age = a; } string getName() { return name; } int getAge() { return age; } };In this example, the class has two private attributes, name and age, and four public methods, setName, setAge, getName, and getAge. This class can be used to create objects that represent persons, and these objects can have their own name and age attributes that are separate from other objects of the same class. The Klass package/library is not a standard C++ library, but rather a potential naming convention for a library or package that contains a collection of related classes.
