Answer :
To declare the class Person in C++, you need to define its attributes and member functions. Here's an example of how you can declare the class:
```cpp
class Person {
private:
std::string lastName; // attribute for last name
std::string firstName; // attribute for first name
char middleInitial; // attribute for middle initial
public:
// constructor to initialize the attributes
Person(const std::string& lastName, const std::string& firstName, char middleInitial) {
this->lastName = lastName;
this->firstName = firstName;
this->middleInitial = middleInitial;
}
// overloaded + operator to combine two Person objects
Person operator+(const Person& otherPerson) const {
std::string newLastName = lastName + "-" + otherPerson.lastName;
return Person(newLastName, firstName, otherPerson.middleInitial);
}
// overloaded << operator to print the Person object
friend std::ostream& operator<<(std::ostream& os, const Person& person) {
os << person.firstName << " " << person.lastName;
return os;
}
};
```
In the class declaration:
- The attributes `lastName`, `firstName`, and `middleInitial` represent the last name, first name, and middle initial of a person, respectively. They are declared as private members.
- The constructor `Person` is used to initialize the attributes of the `Person` class.
- The overloaded `+` operator is used to combine the last names of two `Person` objects, with a hyphen in between, and return a new `Person` object.
- The overloaded `<<` operator is used to print the `Person` object in the desired format.
You can use this class declaration to create instances of the `Person` class and perform the desired operations as shown in your example code.
