Lab Program 1 Array 15CSL38 Data Structures in C Lab

Lab Program 1:   

Download


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