n00b question

Is there a way to declare an array in C so the indexing starts at something besides zero?  Like if I wanted the array to be a[-10] to a[10] instead of a[0] to a[20]?

#define -10 0
#define 9 1
#define 8 2
#define 7 3
#define 6 4
#define 5 5
#define 4 6
#define 3 7
#define 2 8
#define 1 9
#define 0 10
