ICSE Java Programming Average Marks 2018 Q9

Question 9.

Write a program to accept name and total marks of N number of students in two single subscript array name[] and

totalmarks[ ].  

Calculate and print:

(i) The average of the total marks obtained by N Number of students.

[average = (sum of total marks of all the students)/N]

(ii) Deviation of each student’s total marks with the average.

[deviation = total marks of a student – average]
