Nested structure in C programming language

Nested structure in C programming language

In this tutorial, we will discuss the concept of Nested structure in C programming language.

Nested structure is allowed in C programming language.  Nested structure means structure within the another structure. It means we can declare one structure inside another structure.

We can create nesting structure in two way:

1. Declaring a structure variable as Member of another structure – by separated

struct strucuture_Name         
                   {                                        
               <variable_type1> <variable_name>;       
                <variable_type2> <variable_name>;          
                        };                                 
                    

 struct strucuture_Name                          
          {                                                 
       <variable_type1> <variable_name>;                     
       <variable_type2> <variable_name>;                     
          };                            

struct house_address
{
char born_city[30];
int postal_code;
};//one structure
struc student

{

int  stu_id;

char stu_name;

};//another structure

struct Employee
{
int emp_id;
char emp_name;
struct dob
{
int dd;
int mm;
int yyyy;
}

}

When the above code is executed it produces the following result

employee id :14
employee name :jegan sing
employee dob :19/4/2017

Program 2

When the above code is executed it produces the following result
