Please help me with this C++ Program?Strings

Can you please help me with this, Im trying but i cant figure it out

: In this experiment you will investigate the declaration, initialization, and implementation of C++ style strings.

#include

#include

using namespace std;

int main()

{

      string my_name = "Thomas Jefferson";

      string her_name("Michelle Obama");

      string his_name = my_name;

      cout << "my_name = " << my_name << endl;

      cout << "The length of my_name is " << my_name.length() << endl;

      cout << "The size of my_name is " << sizeof(my_name) << endl << endl;

      cout << "her_name = "<

      cout << "The length of her_name is " << her_name.length() << endl;

      cout << "The size of her_name is " << sizeof(her_name) << endl << endl;

      his_name = "Barack Obama";

      cout << "his_name = " << his_name << endl;

      cout << "The length of his_name is " << his_name.length() << endl;

      cout << "The size of his_name is " << sizeof(his_name) << endl << endl;

      string their_name;

      their_name = my_name + " " + her_name

                     + " " + his_name + " " + my_name + " ";

      cout << "their_name = " << their_name << endl;

      cout << "The length of their_name is " << their_name.length() << endl;

      cout << "The size of their_name is " << sizeof(their_name) << endl;

      return 0;

}

Question 1:      What does the length obtained from the stringname.length() member function represent? Is it the same or different for each string?

Question 2:         What does the size obtained from the sizeof() function represent? Is it the same or different for each string?  Why?

Question 3:         Please write three statements from the program which a constructor is used.  Name the type of each constructor (explicit-value, copy, etc).

Question 4: Whats the name of the types of string operations that were performed in the program.

Explanation / Answer

1. It reprasents the total lenght of the string Ex:- my_name.lenght = 16 as "Thomas Jefferson" has 16 characters.

2.It reprasents the amount of memory(in bytes) used for that string. As char takes two bytes in my computer it outputs 8 for the size of my_name.

3.

string her_name("Michelle Obama"); this is explicit value constructor

string my_name = "Thomas Jefferson"; same as above but written differently

string their_name; This is empty string constructor (default constructor) :-Constructs an empty string, with a length of zero characters.

4.

the operations used are called appending operations as the append more than one string
