Answer:

struct student {

   char firstName[50];

   int roll;

   float marks;

} s[10];

int main() {

   int i;

   printf("Enter information of students:\n");

   // storing information

   for (i = 0; i < 5; ++i) {

       s[i].roll = i + 1;

       printf("\nFor roll number%d,\n", s[i].roll);

       printf("Enter first name: ");

       scanf("%s", s[i].firstName);

       printf("Enter marks: ");

       scanf("%f", &s[i].marks);

   }

   printf("Displaying Information:\n\n");

   // displaying information

   for (i = 0; i < 5; ++i) {

       printf("\nRoll number: %d\n", i + 1);

       printf("First name: ");

       puts(s[i].firstName);

       printf("Marks: %.1f", s[i].marks);

       printf("\n");

   }

   return 0;

}
