Q10. Declare and initialize an array of 5 students that store rollno, name and marks in 3 subjects for students.

Q11. Declare a structure to represent a student having the following fields NAME, ROLL NO , PHY, MATHS,

CHEMISTRY, ENGLISH , COMPUTER, TOTAL MARKS , GRADE. Also write a program to read the

fields NAME, ROLL NO, and marks obtained in PHYSICS, CHEMISTRY, MATHS,ENGLISH and

COMPUTER. Find out the total marks obtained by the student and his/her grade. The criteria for grade

calculation is as follows

Total marks Grade

>=450 A+

<450 and >=400 A

<400 and >= 350 B+

<350 and >= 300 B

<300 C

display the result on the screen.
