Data Structure LAB program -01

Design, Develop and Implement a menu-driven Program in C for the following Array operations
1. Creating an Array of N Integer Elements
2. Display of Array Elements with Suitable Headings
3. Inserting an Element (ELEM) at a given valid Position (POS)
4. Deleting an Element at a given valid Position(POS)
5. Exit.
Support the program with functions for each of the above operations.
