Write a C++ program to Create a class student using function overloading
Assignment 21
Write necessary member functions:
a. to accept details of one students
b. to accept details of all students
c. to display details of one student
d. to display details of all students
(Use Function overloading).
Program Code for run:

void display();
void display(Student *s, int n);
