#include<stdio.h>

#include<conio.h>

void main()

{

int english,maths,physics,chemistry;
float total,percentage;

printf(“enter marks of different subjects \n”);

scanf(“%d%d%d%d”,&english,&maths,&physics,&chemistry);

total=english+maths+physics+chemistry;
percentage=(float)total/4; //called type casting to convert total/4 into floating value

printf(“the total marks is=%f\ and percentage=%f\n”,total,percentage);

you can also use like,
percentage=(float)(total/4);
 or
percentage=float(total/4);
you get same output.
