''') Accept marks of three subjects. Print total and average along with whether a candidate has passed or fail. If student secures <= 39 marks in any subject, consider him as fail. Also assigned a subject wise grade based on the following table:

Marks Range Grade

Absent NA

0 – 39 F

40 – 44 P

45 – 49 C

50 – 54 B

55 – 59 B+

60 – 69 A

70 – 79 A+

80 – 100 O'''
