Array of Structures in C

« Prev Next »

In C language allows the use of arrays as structure members. we used arrays of characters inside a structure. Similarly, we are able to use single or multi-dimensional arrays of type int or float. For example, the structure declaration is valid;

Syntax:

struct student      
{   int id;      
    char name[50];      
    int mark1,mark2;      
}s[3];

 

Here, the member subject contains 3 elements, s[0], s[1] and s[2]. These elements can be accessed using appropriate subscripts.

Examples:

#include<stdio.h>  
#include <string.h>      
struct student      
{   int id;      
    char name[50];      
    int mark1,mark2;      
}s[3]; 

void main( )    
{    
	s[1].id=101;    
    strcpy(s[1].name, "Arunkumar");
    s[1].mark1=89;    
    s[1].mark2=58; 
    
    s[2].id=105;    
    strcpy(s[2].name, "Manivannan");
    s[2].mark1=69;    
    s[2].mark2=88; 
    
    s[3].id=102;    
    strcpy(s[3].name, "Deepalakshmi");
    s[3].mark1=79;    
    s[3].mark2=98; 

    for(int i=1;i<4;i++){
    printf( "Student %d id : %d\n",i, s[i].id);    
    printf( "Student %d name : %s\n",i, s[i].name);    
    printf( "Student %d mark1 : %d\n",i, s[i].mark1);    
    printf( "Student %d mark2 : %d\n",i, s[i].mark2); 
    }

}
