What's wrong with the following structure declaration?

    struct automobile {
         int year;
         char model[8];
         int engine_power;
         float weight;
         }


    How many structure variables are defined in the following statement?

    struct x {int y; char z} u, v, w;

    Given a structure declaration

    struct automobile {
         int year;
         char model[8]};

    and two car models, Taurus and Accord, which are made in 1997, initialize an array of two elements, car, that is defined with the automobile structure data type.
    In the following structure declarations, which one is a forward-referencing structure, and which one is a self-referencing structure? (Assume that the structures, employment and education, have not been declared yet.)

    struct member {
         char name[32];
         struct employment *emp;
         struct education *edu;};

    struct list {
         int x, y;
         float z;
         struct list *ptr_list;};
