Initialize a struct with struct types inside

Question

I would like to create a struct Person, which consists of two struct types and a variable inside. How can I initialize and use the struct Person then?

struct name{
   char *firstName;
   char *lastName;
} name;

struct address{
   char *street;
   int number;
} address;

struct person{
   struct name fullName;
   struct address fullAddress;
   int age;
} person;

You can use nested {}.

struct person
{
   struct name fullName;
   struct address fullAddress;
   int age;
} person = 
{
    {
        "First Name", /* person.fullName.firstName */
        "Last Name",  /* person.fullName.lastName */
    },
    {
        "Street",     /* person.fullAddress.street */
        42            /* person.fullAddress.number */
    },
    42                /* person.age */
};

Then you can access to the other members as follow:

person.fullName.firstName;
person.fullName.lastName;
person.fullAddress.street;
person.fullAddress.number;
person.age;

For a 18-year-old John Doe, living at address, 42

struct person{
   struct name fullName;
