Define a new type struct dog with the following elements:

• name, type = char *
• age, type = float
• owner, type = char *

Write a function that initialize a variable of type struct dog

• Prototype: void init_dog(struct dog *d, char *name, float age, char *owner);

Write a function that prints a struct dog

• Prototype: void print_dog(struct dog *d);
• Format: see example bellow
• You are allowed to use the standard library
• If an element of d is NULL, print (nil) instead of this element. (if name is NULL, print Name: (nil))
• If d is NULL print nothing.

• Define a new type dog_t as a new name for the type struct dog.

Write a function that creates a new dog.

• Prototype: dog_t *new_dog(char *name, float age, char *owner);
• You have to store a copy of name and owner
• Return NULL if the function fails

Write a function that frees dogs.

• Prototype: void free_dog(dog_t *d);
