void display(struct student *p);

struct student

{

            char name[20];

            int rollno;

            float mark;

};

int main()

{

            struct student S1;

            printf("\nEnter name rollno and mark of a student:");

            scanf("%s %d %f", S1.name, &S1.rollno, &S1.mark );

            display(&S1);

}

void display(struct student *p)

{

    printf("\n Name is %s \n Rollno is %d \n Mark is %f", p->name, p->rollno, p->mark );

}
