Structure with Pointers in C

Syntax to declare structure type pointer variable is:

struct Struct_name  *var;

var represents pointer variable of structure.

We can use pointer variable of structure to access its elements pointer in two ways:

• (->) arrow operator
• (.) dot operator
  

Program to demonstrate use of pointer variable of a structure.

#include<stdio.h> struct emp { int empid; float sal; }; int main() { struct emp e1={101,50000.00}; struct emp *e2; e2=&e1; printf(“\nEmpid=%d”,e2->empid);  printf(“\nSalary=%f”,(*e2).sal);return(0); }

Output

Empid=101 Salary=50000.00
