Write a program to input sum of 5 subjects and display percentage and division

To find percentage, divide the sum of marks obtained in each subject by total marks and then  multiply by 100. For division, if percentage>60, "first division", if percentage>=45 and less than 60, "second division", if percentage>=30 and less than 45, "third division" else fail.

#include<stdio.h>

void main()

{

   int sci, math, eng, hin, comp, sum, total=500;

   float per;

  

   printf("Enter marks obtained in five subjects");

   scanf("%d %d %d %d %d", &sci, &math, &eng, &hin, &comp);

   

   sum= sci+math+eng+hin+comp;

   printf("\nSum=%d",sum);

   per=(sum/500)*100;

   printf("Percentage obtained is %f",per);

   

   if(per>=60)

   printf("\nFirst division");

   else if(per>=45 && per<60)

   printf("\nSecond division");

   else if(per>=30 && per<45)

   printf("\nThird division");

   else

   printf("\n Fail");

  }
