Write a program to record 3 grades of 5 students with the following information :
Roll No, Name, Exam1,Exam2,Exam3,Average,Approved(YES/NO).
The program must have a menu where:
1) Students and grades are recorded
2) Search student ( show students name and Roll No)
3) Delete student
4) Show averages ( show student name and his average )
5 ) Show approved students ( only show students that have approved, the minimum average is : 70)
------------------------------------------------------------
I WOULD LIKE HELP WITH 2) AND 3)
------------------------------------------------------------
I have done this modifying programs that we have done from previous classes.
P.S. Sorry if my english is bad.
EDIT: Not sure, but i think the correct word instead of Roll no would be enrollment number.
