C program to demonstrate accessing a structure using a pointer

In this article we will learn to implement a C program to demonstrate accessing a structure using a pointer. A C program is provided below that illustrates how to access a structure using a pointer.

Program is as follows:

/*
 * C program to demonstrate accessing a structure using a pointer
 * Author: P.S.SuryaTeja
*/
#include <stdio.h>
#include <conio.h>
#include <math.h>
#include <stdlib.h>
#include <string.h>

struct student
{
	int id;
	char name[20];
};

int main(int argc, char **argv)
{
	struct student *stp;
	struct student st;
	stp = &st;
	printf("Enter student id: ");
	scanf("%d", &stp->id);  //&stp->id is same as writing &(*stp).id
	fflush(stdin);
	printf("Enter student name: ");
	gets(stp->name);
	printf("\n***Student Details***");
	printf("\nStudent id: %d", stp->id);
	printf("\nStudent name: ");
	puts(stp->name);
    getch();
    return 0;
}

Input and output for the above program is as follows:

Enter student id: 101
Enter student name: teja

***Student Details***
Student id: 101
Student name: teja
