Write a program that define a structure student, with members rollno, name and marks. Also define functions to input and show student data.

#include<stdio.h>

struct student

{

int roll_no;

char name[20];

float marks;

};

struct student input();

void display(struct student);

void main()

{

struct student r;

clrscr();

r=input();

display(r);

getch();

}

struct student input()

{

struct student s1;

printf("Enter student data\n");

scanf("%d",&s1.roll_no);

fflush(stdin);

gets(s1.name);

scanf("%f",&s1.marks);

return(s1);

}

void display(struct student s)

{

printf("roll_no=%d\n",s.roll_no);

printf("name=%s\n",s.name);

printf("marks=%f\n",s.marks);

}
