c structure program example accept structure element and print using function

c program structure using function

write a simple c program which accept structure element and print it  using function. (use call by value )

 how to write a simple c program which accept structure element and print it  using function use call by value and call by reference example with source code , structure using function and pointer program example with source code.

#include<stdio.h>

#include<conio.h>

struct stud{ int rno;char nm[20];};

void pr(struct stud s);

void main()

{

 struct stud s1;

  clrscr();

  printf("enter structure element : \n ");

  scanf("%d",&amp;s1.rno);

  fflush(stdin);

  gets(s1.nm);

  pr(s1);

  getch();

}

void pr(struct stud s)

{ printf("\n_____________________\n");

 printf("id=%d  Name=%s",s.rno,s.nm);

}

output:
