Answer 1

Answer:

1. struct Appointment {
2.    char name[20];
3.    struct Date d;
4.    struct Time t;
6. };
8. struct Date{
9.    int year;
10.    int month;
11.    int day;
12. };
14. struct Time{
15.    int hour;
16.    int minutes;
17.    int seconds;
18. };

Explanation:

To create a struct data type, let use the keyword "struct" and followed with the variable name, Appointment (Line 1).  

Next create the string member, name (Line 2).

Next we need to  include two other struct data types (Date and Time) as part of the member of the existing struct. To do so, we can try to define the struct for Date (Line 8 - 12) and Time (Line 14 - 18) separately.

At last, we include the struct Date & Time into the Appointment struct (Line 3-4)
