0x0E. C - Structures, typedef

Learning objectives for this project:

• What are structures, when, why and how to use them
• How to use typedef

Tests ✔️

• tests: Folder of test files. Provided by Holberton School.

Header File 📁

• dog.h: Header file containing definitions and prototypes for all types and functions written in the project.

Type/File	Defintion/Prototype
struct dog	char *name float age char *owner
typedef dog_t	struct dog
1-init_dog.c	void init_dog(struct dog *d, char *name, float age, char *owner);
2-print_dog.c	void print_dog(struct dog *d);
4-new_dog.c	dog_t *new_dog(char *name, float age, char *owner);
5-free_dog.c	void free_dog(dog_t *d);

Tasks 📃

• 0. Poppy

  • dog.h: Header file that defines a new type struct dog with the following elements:
    • char *name
    • float age
    • char *owner

• 1. A dog is the only thing on earth that loves you more than you love yourself

  • 1-init_dog.c: C function that initializes a variable of type struct dog.

• 2. A dog will teach you unconditional love. If you can have that in your life, things won't be too bad

  • 2-print_dog.c: C function that prints a struct dog.
    • If an element of d is NULL, the function prints (nil) instead of the element.
    • If d is NULL, the function prints nothing.

• 3. Outside of a dog, a book is a man's best friend. Inside of a dog it's too dark to read

  • dog.h: Header file that defines a new type dog_t as a new name for the type struct dog.

• 4. A door is what a dog is perpetually on the wrong side of

  • 4-new_dog.c: C function that creates a dog.
    • Returns NULL if the function fails.

• 5. How many legs does a dog have if you call his tail a leg? Four. Saying that a tail is a leg doesn't make it a leg

  • 5-free_dog.c: C function that frees dogs.
