-SHWETA GUPTA
Introduction The following program creates a
data type student which includes
the following members:
1. Name
2. Roll no.
3. Marks in 5 subjects
4. Total
5. Average
6. Grade
It arranges the students in
ascending order of total marks
obtained.
It also finds the subject
toppers and overall topper.
Certificate This is to certify that
Shweta Gupta studying in
class 11 C has successfully
completed the computer
science assignment for the
year 2014-15.
