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.
