Pointers to Structs

The C programming language allows you to create pointers not only to regular data types but also to structures (since a structure is a custom data type).

Declaration and initialization of a pointer looks like this:

struct <name_of_struct>
{
    <field_of_struct>;
};

struct <name_of_struct>* <name_of_pointer>;

If <name_of_pointer> is a pointer to a structure,
then *(<name_of_pointer>) is the structure itself.

To access the fields of a structure through a pointer, you must use the -> operator.

Note

"->" is an analogue of the structure access operator .

#include <stdio.h>

// structure declaration
struct Point {
    int x;
    int y;
};

int main() {
    // create a structure variable of Point type
    struct Point p1;
    p1.x = 10;
    p1.y = 20;

    // create a pointer to a structure of type Point and assign it the address of variable p1
    struct Point* ptr = &p1;

    // Access structure members via pointer by `->` operator
    printf("Coordinates: (%d, %d)\n", ptr->x, ptr->y);

    return 0;
}

  2. Initialize the structure worker and fill the fields;
  3. Declare and initialize a pointer ptr to a worker;
  4. Display information about the worker.
