------------------------------------------------ In C++ Language:

Suppose I have a class named `Person`. Here is how I would like to use the class:

```cpp
// Create a person named Dave Smith
Person dave("Smith", "Dave", 'R');

// Create a person named Gal Gadot
Person gal("Gadot", "Gal", 'G');

// Dave and Gal get married
gal = dave + gal;
dave = dave + gal;

// Print Gal and Dave's new married name
cout << gal << endl;
cout << dave << endl;
```

This will output the following:

```
Gal Smith-Gadot
Dave Smith-Gadot
```

Write the class declaration for `Person`.

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.
