Defining an array of structures
Returning to our AFL project example,
we can now define and gather together its related data with:
// DEFINE THE LIMITS ON PROGRAM'S DATA-STRUCTURES
#define MAX_TEAMS 24
#define MAX_TEAMNAME_LEN 30
....
struct {
char teamname[MAX_TEAMNAME_LEN+1]; // +1 for null-byte
// STATISTICS FOR THIS TEAM, INDEXED BY EACH TEAM'S 'TEAM NUMBER'
int played;
int won;
int lost;
int drawn;
int bfor;
int bagainst;
int points;
} team[MAX_TEAMS]; // DEFINE A 1-DIMENSIONAL ARRAY NAMED team
|
We now have a single (1-dimensional) array,
each element of which is a structure.
We often term this an array of structures.
Each element of the array has a number of fields,
such as its teamname (a whole array of characters)
and an integer number of points.
