#include<stdio.h>
int main(void)
{
float m1,m2,m3,m4,total,per;
char grade;
printf("Enter marks of 4 subjects : ");
scanf("%f%f%f%f",&m1,&m2,&m3,&m4);
total=m1+m2+m3+m4;
per=total/4;
if(per>=85)
grade='A';
else if(per>=70)
grade='B';
else if(per>=55)
grade='C';
else if(per>=40)
grade='D';
else
grade='E';
printf("Percentage is %f,Grade is %c\n",per,grade);
