_STANDARD C: AN UPDATE_
by Rex Jaeschke 

Example 1:

extern int n;
void f(int m, int x[m][n])
{
    char c[m];
    int (*p)[n];
}


Example 2:

(a)

int i[20] = {5, 10, [17] = 50, 60};


(b)

enum color { red, green, blue };
unsigned int total[] = {

   [red]   = 100,
    [blue]  = 200,
    [green] = 50
};


(c)

struct date {
    int year;
    int month;
    int day;
};
struct date birthday = {
    [month] = 1,
    [day]   = 2,
    [year]  = 1950
};

Example 3:

struct Point {
    int x;
    int y;

};
void drawline(struct Point *, struct Point *);
void f(int x2, int y2)
{
/*1*/   const int *p = (int []){x2, 5, y2, 4};
/*2*/   drawline(&(struct Point){0,0}, &(struct Point){x2,y2});
}
