Array of Structure - Structure in C

We can also use a Array as Structure variable is called Array of Structure.

Syntax:

 struct structure_name
{
 data_type array_variable1;
 data_type array_variable2;
---------------------------------
 data_type array_variableN;
}structure array_variable ;   // Global Array variable Declaration. 

OR

 struct structure_name structure_array_variable; // Local Array Variable declaration.


Example :

 struct student
{
 char name[20];
 int roll;
 float marks;
}s[10]; // Global Array variable Declaration. 

OR

 struct student s[5]; // Local Array Variable declaration.

• Here, s[10] is a variable of structure student and store the information of 10 students on index s[0],s[1],s[2],…s[4].
• Every index have a information of a student.
• These elements can be accessed with its appropriate subscripts/indexes.

Example of Array of Structure:

 #include<stdio.h>
 #include<conio.h>

 //Structure is Created  with Array
 struct abc
 {

 char name[20];
 int rollno;
 int per;
 };
 // Initialization a Structure
 void main()
 {

 int i;
 struct abc s1[5];
 clrscr();
 for(i=0;i<5;i++)
 {
 printf("Enter the Information of Student No. %d",i+1);
 printf("\n Enter the Name of the Student-");
 scanf("%s",s1[i].name);
 printf("\n Enter the Roll No. of the Student-");
 scanf("%d",&s1[i].rollno);
 printf("\n Enter the Percentage of the Student-");
 scanf("%d",&s1[i].per) ;
 }
 // Accessing structure member
 for(i=0;i<5;i++)
 {
 printf(" \nThe Information of Student No. %d",i+1);
 printf("\n Name of the Student--%s",s1[i].name);
 printf("\n Roll No. of the Student--%d",s1[i].rollno);
 printf("\n  Percentage of the Student--%d",s1[i].per);
 }
 getch();
 }
