More Detail

Structure is a collection of different datatype variables, grouped together under a single name.

Features of structure

The features of structure are explained below −

It is possible to copy the contents of all structure elements of different datatypes to another structure variable of its type by using an assignment operator.
For handling complex datatypes, it is better to create a structure within an another structure, which is called as the nested structures.
It is possible to pass an entire structure, individual elements of a structure and an address of structure to a function.
It is also possible to create the structure pointers.

Declaration of structures

The general form of structure declaration is as follows −

datatype member1;
struct tagname{
   datatype member2;
   datatype member n;
};

Here, struct is the keyword.

tagname specifies name of structure.

member1, member2 are the data items.

For example,

struct book{
   int pages;
   char author [30];
   float price;
};

Example

Following is the C program for structure in local scope −

Live Demo

#include<stdio.h>
struct{
   char name[20];
   int age;
   int salary;
   char add[30];
}emp1,emp2;
int manager(){
   struct{
      char name[20];
      int age;
      int salary;
      char add[50];
   }manager ;
manager.age=27;
if(manager.age>30)
   manager.salary=65000;
else
   manager.salary=55000;
   return manager.salary;
}
int main(){
   printf("enter the name of emp1:");
   //gets(emp1.name);
   scanf("%s",emp1.name);
   printf("
enter the add of emp1:");
   scanf("%s",emp1.add);
   printf("
enter the salary of emp1:");
   scanf("%d",&emp1.salary);
   printf("
enter the name of emp2:");
   // gets(emp2.name);
   scanf("%s",emp2.name);
   printf("
enter the add of emp2:");
   scanf("%s",emp2.add);
   printf("
enter the salary of emp2:");
   scanf("%d",&emp2.salary);
   printf("
emp1 salary is %d",emp1.salary);
   printf("
emp2 salary is %d",emp2.salary);
   printf("
manager salary is %d",manager());
   return 0;
}

Output

When the above program is executed, it produces the following result −

enter the name of emp1:hari
enter the add of emp1:hyderabad
enter the salary of emp1:4000
enter the name of emp2:lucky
enter the add of emp2:chennai
enter the salary of emp2:5000
emp1 salary is 4000
emp2 salary is 5000
manager salary is 55000
