Define a class named student with four member variables 3 st

Define a class named student with four member variables: 3 strings for student ID, First Name, and Last name. Write necessary accessor and mutator functions. Also, write a default constructor that sets student ID, first and last name to your own info. Write a test program to test the class. Add three constructors to the previous class. If you pass only one string that is the student ID. If your pass two strings, they are the first and last name. If you pass three strings, they are the ID, first and last name respectively.

#include <iostream>

using namespace std;

// Class Declaration
class Student

//Access - Specifier
private:

//Varibale Declaration

string firstName;
string lastName;

public :
// constructor to set all this three parameter
Student(string stdId, string fstName, string lstName);
Student(string stdId);
Student(string stdId, string fstName);

//Accessor functions
string getStudentId();
string getFirstName();
string getLastName();

//mutator functions
void setStudentId(string stdId);
void setFirstName(string frstName);
void setLastName(string lstName);
