/*Qus 3: write a Java program to create marks sheet with all grades and print the overall grade as shown below and the Grading details are as follows:
Grade A+: Marks>=90
Grade A: 90>Marks>=80 Grade B+: 80>Marks>=70 Grade B: 70>Marks>=60 Grade C: 60>Marks>=35
Fail: 35>Marks


Subject	Max Marks	Obtained marks.	Grade
Maths	100	91.	A+
DBMS	100	84.	A
C language	100	74.	B+
Java	100	64.	B
Html	100	54.	C
php
Result :.	FAIL	100	34.	FAIL
Note:- Marks are dynamic input need to read from the keyboard.*/
