413f Here is part 413 part d modify the code to produce part

4-13f. Here is part 4-13 part d, modify the code to produce parts b (separate header file student4-13.h for the structure definition, see fields in code to see data fields) and parts e and f (separate function for the printing of the array and pass the address of the array to a student pointer that will increment through the array, printing the student address label by accessing the fields through the arrow operator and making the for loop into a pointer comparison while loop). Submit the final part f main .cpp and student4-13.h.

**     d.   with an array of student structures

**     b.   with the structure definition in a separate header file
*      e.   with a function to print the array
**     f.   with a pass by reference (pointer to the array) to the function (using the arrow operator), using the pointer comparison while loop

#include <iostream>
using namespace std;

   char street[256];
   char city[256];
   char state[256];
   int zip;
};

   string first;
   string last;
   address home;
   int year;
};

// main.cpp

#include <iostream>
#include \"student4-13.h\" // define student and address structures
using namespace std;

void print(student *s, int size){
   int j = 0;
   while(j < size) // change to while pointer comparison loop
   {

       cout << (s + j)->home.city << \", \" << (s + j)->home.state << \" \" << (s + j)->home.zip << endl;
       j++;
