Copying Structures 
Copying structure is directly done by assignment operator(=).

Example
strc_object_copy = strc_object;
Program
#include
struct student {
int rno;
char student_name[30];
};#include
struct student {
   int rno;
   char student_name[30];
};
void main(){
   //initialize values to structure
   struct student data = {1001,"Ramesh"};
    //copy structure value to another structure
   struct student copy_data;
   copy_data = data;
   printf("%d : %s",copy_data.rno,copy_data.student_name);
}
void main(){
   //initialize values to structure
   struct student data = {1001,"Ramesh"};
   //copy structure value to another structure
   struct student copy_data;
   copy_data = data;
   printf("%d : %s",copy_data.rno,copy_data.student_name);
}
Output 
1001 : Ramesh
