Write a C program to input marks of five subjects Physics, Chemistry, Biology, Mathematics and Computer, calculate percentage and grade according to given conditions:
If percentage >= 90% : Grade A
If percentage >= 80% : Grade B
If percentage >= 70% : Grade C
If percentage >= 60% : Grade D
If percentage >= 40% : Grade E
If percentage < 40% : Grade F
Example
Input
Input marks of five subjects: 95 95 97 98 90
Output
Percentage = 95.00 Grade A
/**
* C program to enter marks of five subjects and find percentage and grade
*/
#include <stdio.h>

{
int phy, chem, bio, math, comp;
float per;
/* Input marks of five subjects from user */
printf("Enter five subjects marks: ");

/* Calculate percentage */
per = (phy + chem + bio + math + comp) / 5.0;
printf("Percentage = %.2f\n", per);
/* Find grade according to the percentage */
