C program to print student data-using struct ( C program Coding )

Coding-
#include<stdio.h>
#include<conio.h>
struct student
   {
   int rollno;
   char name[20];
   int age;
   };
   struct student input studentdata();
  void showstudentdata (struct student);
 void main()
   {
   struct student s1;
   clrscr();
   s1=inputstudentdata();
   showstudentdata(s1)
  getch();
  }
struct student inputstudentdata()
  {
  struct student s;
printf("Enter roll no,name and age");
scanf("%d",&s,roll no);
fflush (stdio);
gets(s.name);
scanf("%d",&s. age);
return(s);
}
void showstudentdata (structstudent ss);
{
printf("\n studentdata");
print("\n rollno =%d",ss.roll no);
printf("\n name=%s",ss.name);
printf("\n age=%d",ss.age);
}

OUTPUT-
Enter roll no,name and age 12345
Amar
19
student data
roll no =12345
name=Amar
age=19
