Hint: (c/5) = (f - 32) / 9Write a program to accept name and total marks of N number of students in two single subscript arrays 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]
