point.comStructure in C
In C, a structure is a collection of different data types that are grouped together and each element in a structure is called as a member. Data types can be int, char, float, double and long double and etc.
- In order to access structure members in C, the structure variable should be declared.
- Structure variables can be declared for same structure and the memory will be allocated for each variable separately.
- Initialize a structure to null while declaring, when if we don’t assign any values to structure members.
Syntax:
struct structure_name {
data_type member 1;
data_type member 2;
.
.
data_type member n;
} [one or more structure variables];
Example:
#include <stdio.h>
#include <string.h>
struct student
{ int id;
char name[50];
int mark1,mark2;
}s1,s2,s3;
void main( )
{
s1.id=101;
strcpy(s1.name, "Arunkumar");
s1.mark1=89;
s1.mark2=58;
s2.id=105;
strcpy(s2.name, "Manivannan");
s2.mark1=69;
s2.mark2=88;
s3.id=107;
strcpy(s3.name, "Deepalakshmi");
s3.mark1=98;
s3.mark2=78;
printf( "Student 1 id : %d\n", s1.id);
printf( "Student 1 name : %s\n", s1.name);
printf( "Student 1 mark1 : %d\n", s1.mark1);
printf( "Student 1 mark2 : %d\n", s1.mark2);
printf( "Student 2 id : %d\n", s2.id);
printf( "Student 2 name : %s\n", s2.name);
printf( "Student 2 mark1 : %d\n", s2.mark1);
printf( "Student 2 mark2 : %d\n", s2.mark2);
printf( "Student 3 id : %d\n", s3.id);
printf( "Student 3 name : %s\n", s3.name);
printf( "Student 3 mark1 : %d\n", s3.mark1);
printf( "Student 3 mark2 : %d\n", s3.mark2);
}
