Dot(.) operator is used to access the data using normal structure variable and arrow (->) is used to access the data using a pointer variable. You have learned how to access structure data using normal variables in C – Structure topic. So, we are showing here how to access structure data using the pointer variable in the below C program.
EXAMPLE PROGRAM FOR C STRUCTURE USING POINTER:
In this program, “record1” is a normal structure variable and “ptr” is the pointer structure variable. As you know, Dot(.) operator is used to access the data using the normal structure variable, and arrow(->) is used to access data using the pointer variable.
#include <stdio.h>
#include <string.h>
struct student {
int id;
char name[30];
float percentage;
};
int main() {
int i;
struct student record1 = {1, “Raju”, 90.5};
struct student *ptr;
ptr = &record1;
printf(“Records of STUDENT1: \n”);
printf(” Id is: %d \n”, ptr->id);
printf(” Name is: %s \n”, ptr->name);
printf(” Percentage is: %f \n\n”, ptr->percentage);
return 0;
}
OUTPUT:
| Records of STUDENT1: Id is: 1 Name is: Raju Percentage is: 90.500000 |
