Structures

Structures

• Collection of related variables
• derived data types
• Contain variables of many different data types
• Individual structure elements are known as members
• The general syntax structure declaration is:

struct name_tag{
member_1;
member_2;
member_3;
...
member_n;
};

• "struct" is a keyword
• name_tag is a name that identifies the structure
• The individual members can be ordinary variables, pointers, arrays and other structures
• Example

struct student{
int matrikno;
char name[40];
float height;
};

• A structure member can be accessed by a dot operator
• The syntax of a dot operator is:
  • variable.member
• where variable refers to the name of a structure type variable and member represents to the name of a member within a structure
• Example

#include

struct studentdate{
int matno;
int month;
int date;
int year;
};

int main (void){

studentdate joiningdate;

scanf("%d", &joiningdate.matno);
scanf("%d", &joiningdate.month);
scanf("%d", &joiningdate.date);
scanf("%d", &joiningdate.year);

printf("%d\n", joiningdate.matno);
printf("%d\n", joiningdate.month);
printf("%d\n", joiningdate.date);
printf("%d\n", joiningdate.year);

return 0;
}
