Create a file called mytypes.c, and write declarations for the following
types in it: 

(1) A struct for a complex number, called _complex_num_t, which has a
    double for the real part (called real_part) and a double for the
    imaginary part (called imaginary_part). 
    Then, create a typedef for this struct which makes complex_num_t an
    alias for struct _complex_num_t. 
(2) An enum for animals, called _animal_t which enumerates the following
    constants: CAT FISH SNAKE DOG HORSE
    Create a typedef for this enum which makes animal_t an alias for
    enum_animal_t

Find a partner who is on the same problem, and check each other's
syntax. Then submit your mytypes.c file.
