P191. Program to store 5 student database which contains 3 information ( roll no – name – marks ) in unsorted order, ask the user for input in which way he/she needs the data. 1 – Display name of highest marks student. 2 – Even roll number information’s. 3 – Name ending with a vowel – display its information.
