Structures Containing Arrays
187
Naturally, it is possible to set up an array of dateAndTime structures, as is done with the
following declaration:
struct dateAndTime events[100];
The array events is declared to contain 100 elements of type struct dateAndTime.The
fourth dateAndTime contained within the array is referenced in the usual way as
events[3],and the ith date in the array can be sent to your dateUpdate function as follows:
events[i].sdate = dateUpdate (events[i].sdate);
To set the first time in the array to noon, the series of statements
events[0].stime.hour = 12;
events[0].stime.minutes = 0;
events[0].stime.seconds = 0;
can be used.
Structures Containing Arrays
As the heading of this section implies, it is possible to define structures that contain
arrays as members. One of the most common applications of this type is setting up an
array of characters inside a structure. For example, suppose you want to define a structure
called month that contains as its members the number of days in the month as well
as a three-character abbreviation for the month name.The following definition does
the job:
struct month
{
int numberOfDays;
char name[3];
};
This sets up a month structure that contains an integer member called numberOfDays and
a character member called name.The member name is actually an array of three characters.You
can now define a variable to be of type struct month in the normal fashion:
struct month aMonth;
You can set the proper fields inside aMonth for January with the following sequence of
statements:
aMonth.numberOfDays = 31;
aMonth.name[0] = 'J';
aMonth.name[1] = 'a';
aMonth.name[2] = 'n';
