The marks obtained by 50 students in a subject are tabulated as follows:-
| Name | Marks |
|---|---|
| ….. | ….. |
| ….. | ….. |
| ….. | ….. |
Write a program to input the names and marks of the students in the subject.
Calculate and display:
(a) The subject average marks (subject average marks = subject total/50).
(b) The highest marks in the subject and the name of the student. (The maximum marks in the subject are 100.)
