Ienumerable Implementation for User Classes

---

This project show how You can implement Ienumerable interface for Your own classes.

---

Purpose

The goal of this project show how You can obtain foreach loop for Your class object.

}

Ronald Kuman
Fran Raykard
Patrick Kluvert
Rud Gulid

Showing by foreach loop with per.data
Ronald Kuman
Fran Raykard
Patrick Kluvert
Rud Gulid

Showing by foreach for person class, by implementing IEnumerable interface
