C# In the Person class, add three property accessors:

A FirstName accessor that is a string that is responsible for getting and setting the protected firstName member variable.

A LastName accessor that is a string that is responsible for getting and setting the protected lastName member variable.

A FullName accessor that is a string that returns the first name concatenated with the last name with a space in between for its getter. There should be no setter.

using System;

namespace Exercise {

public class Person {

string firstName;

string lastName;

// TODO: Accessors

public Person() {

this.firstName = "";

this.lastName = "";

}

public Person(string firstName, string lastName) {

this.firstName = firstName;

this.lastName = lastName;

}

}

}
