C Arrays within Structure

Sometimes, arrays may be the member within structure, this is known as arrays within structure. Accessing arrays within structure is similar to accessing other members.

Purpose of Array within Structure

When you find yourself to store a string value, then you have to go for array within structure. because your name comes under character data type alone, thus array is capable of storing data of same data type.

C program - Arrays within Structure (Easy)

Lets code array within structure and have some fun

array-within-struct.c
#include <stdio.h>
int main()
{
struct student {
char name[30];
int rollno;
} stud;
printf ("Enter your RollNo : ");
scanf ("%d",&stud.rollno);
printf ("\nEnter your Name : ");
scanf ("%s", stud.name);
printf ("\nRollNo : %d\n Name : %s", stud.rollno, stud.name);
return 0;
}
  • Enter your RollNo : 16
  • Enter your Name : Jiju
  • RollNo : 16
  • Name : Jiju

Note:

Here stud act as an object for a structure student, so it's possible for us to access any member inside a student using our object stud.

C program - Arrays within Structure (medium)

Lets code array within structure and have some fun

array-within-struct-1.c
#include <stdio.h>
int i;
struct student {
char name[30];
int rollno;
} stud[3];
for(i=0; i<3; i++)
{
printf ("\nEnter your RollNo : ");
scanf ("%d",&stud[i].rollno);
printf ("\nEnter your Name : ");
scanf ("%s", stud[i].name);
}
printf ("\nList of all records");
for (i=0; i<3; i++)
{
printf ("\nRollNo : %d\n Name : %s", stud[i].rollno, stud[i].name);
}
return 0;
}
  • Enter your RollNo : 1
  • Enter your Name : Abu
  • Enter your RollNo : 2
  • Enter your Name : Ben
  • Enter your RollNo : 3
  • Enter your Name : Charlie
  • List of all records
  • RollNo : 1
  • Name : Abu
  • RollNo : 2
  • Name : Ben
  • RollNo : 3
  • Name : Charlie

Note:

Here stud [3] act as an object array for a structure student, so it's possible for us to access any member inside a student using our object stud [n].
