C言語でポインタ構造の概念を適切な例を用いて説明します。

struct tagname *ptr;

Ptr-> membername;

#include<stdio.h>
struct student{
   int sno;
   char sname[30];
   float marks;
};
main ( ){
   struct student s;
   struct student *st;
   printf("enter sno, sname, marks:");
   scanf ("%d%s%f", & s.sno, s.sname, &s. marks);
   st = &s;
   printf ("details of the student are");
   printf ("Number = %d</p><p>", st ->sno);
   printf ("name = %s</p><p>", st->sname);
   printf ("marks =%f</p><p>", st ->marks);
   getch ( );
}

enter sno, sname, marks:1 priya 34
details of the student areNumber = 1
name = priya
marks =34.000000
