Write a program using structure within structure.​

Introduction

In this program, we will learn to use a structure within a structure.

Algorithm

  1. Start
  2. Declare a structure called outer_struct, and it stores information about a student.
  3. Declare a structure called inner_struct, and it stores information about a student.
  4. Intiliaze the student details.
  5. Print the student details.
  6. End

Code

Practical-12.c

#include <stdio.h>

void main()
{
  /* STRUCTURE within STRUCTURE */

  /* first define the outer structure */
  struct outer_struct {
      char name[20];
      int age;

      /* now define the inner structure */
      struct inner_struct {
          int marks;
          char grade;
      } inner;
  } outer;

  /* assign values to outer structure */
  strcpy(outer.name, "Naruto");
  outer.age = 20;
  /* assign values to the inner structure */
  outer.inner.marks = 80;
  outer.inner.grade = 'A';

  /* display the structure member values */
  printf("name: %s\n", outer.name);
  printf("age: %d\n", outer.age);
  printf("marks: %d\n", outer.inner.marks);
  printf("grade: %c\n", outer.inner.grade);

}

Output

name: Naruto
age: 20
marks: 80
grade: A
Explanation

In this program, we have used a structure within a structure. We have defined a structure called outer_struct, and it stores information about a student. We have defined another structure called inner_struct, and it stores information about a student. We have initialized the student details. We have printed the student details.
