5. Structure and Pointers
• Pointer to structure: Pointer which stores address of structure is called as “Pointer to
Structure “.
• Explanation :
1. sptr is pointer to structure address.
2. -> and (*). both represents the same.
3. These operators are used to access data member of structure by using structure’s
pointer.

6. • Example: Program to create a structure and display the content using
pointer.
#include<stdio.h>
struct team {
char *name;
int members;
char captain[20];
}
t1 = {"India",11,"Dhoni"} , *sptr = &t1;
int main()
{
printf("nTeam : %s",(*sptr).name);
printf("nMemebers : %d",sptr->members);
printf("nCaptain : %s",(*sptr).captain);
return 0;
}

Summary
A structure can be passed to
any function from main
function or from any sub
function.
Structure definition will be
available within the function
only.
It won’t be available to other
functions unless it is passed to
those functions by value or by
address
Else, we have to declare
structure variable as global
variable. That means, structure
variable should be declared
outside the main function. So,
this structure will be visible to
all the functions in a C program.
To access members of a
structure using pointers, we use
the -> operator.
We can also initialize the array
of structures using the same
syntax as that for initializing
arrays.
