struct array{   *base;    /* array element Base address, assigned by Initarray *   / int Dim;           /* Array Dimensions *   / int *bounds;       /* array dimension base address, assigned by Initarray *   / int *constants;    /* array image function constant base address, allocated by Initarray */};
For three-dimensional array a[3][2][2]Baseis a pointer to the array element that stores the memory: a[0][0][0], a[0][0][1], a[0][1][0].........dim Dimension, Save:3the memory that bound points to is stored:3 2 2  //this is [3][2][2]the memory that constants points to is stored:4 2 1  //contants[2]=1 contants[1]= 1 x 2 =2 contants[0]= 2 x 2 =4

Constants[] is calculated.
for (i=dim-2; i>=0; i--)
Constants[i] = bound[i+1] * constants[i+1];
