C++ Programming help

Struct Student{int id; string first name lastname;int courses;double gpa}

int main

const int MAX_STUDENTS=3

Student studentarr[MAX_STUDENTS]. //array should be scalable. If I change the number program should work

menu()

1 display student information

2 edit student information

3 reset student information

4 Exit

Case 1

display_studentinfo()

This function should display all the three students information like this

Student 1

int id  0

first name not entered

case 2

edit-info()

Which student info you want to update?

here user can upadate student info

case3 set to default

All student information should set back to initial condition

case 4

exit

All four cases should be function calls. Pass array to functions. it should be scalable. I tried. but got stuck. Please help

struct Student

{

int id;

string first_name,last_name;
