Write a C++ program to input marks of five subjects Physics, Chemistry, Biology, Mathematics, and Computer.
Calculate the percentage and grade according to the following rules:
Percentage >= 90% : Grade A
Percentage >= 80% : Grade B
Percentage >= 70% : Grade C
Percentage >= 60% : Grade D
Percentage >= 40% : Grade E
Percentage < 40% : Grade F

Output
Enter marks of computer
90
enter marks of English
92
enter marks of bio
97
enter marks of maths
96
enter marks of physics
99
Grade=A
