Structures and unions are user-defined data types in C that allow developers to group variables of different data types into a single unit.

struct Person 
    int age;
    char* name;
;
struct Person person;
person.age = 30;
person.name = "John";

In the example above, struct Person is a user-defined data type that consists of an age field and a name field.

Unions are similar to structures, but all fields in a union share the same memory space. advanced c programming by example pdf github

union Data 
    int i;
    float f;
;
union Data data;
data.i = 10;
printf("%d\n", data.i); // prints 10
data.f = 3.14;
printf("%d\n", data.i); // prints 0 (garbage value)

In the example above, union Data is a user-defined data type that consists of an i field and an f field. The i field is overwritten by the f field when data.f is assigned a value.

Sean Barrett’s stb headers (e.g., stb_ds.h for hash tables, stb_sprintf.h for fast formatting) are advanced C by example. Reading stb_ds.h teaches:

Functions are first-class citizens in C, and advanced C programming involves mastering function pointers and function pointer arrays. In the example above, struct Person is a

int add(int x, int y) 
    return x + y;
int (*fp)(int, int) = add;
printf("%d\n", fp(2, 3)); // prints 5

In the example above, fp is a function pointer that points to the add() function.
