It means to declare or dereference a pointer to a pointer. For example:

int x = 5;

int *xPtr = &x;

int **xPtrPtr = &xPtr;

printf("%d\n", **xPtrPtr);

Double asterisks ** generally means you are to repeat the instructions within. You might find two sets of ** where the instructions between the two sets are repeated the number of times specified, or you might read, "repeat from **" a certain number of times. When you find double asterisks that might also mean that there is another set of repeated instructions which use either single asterisks or some other means of identifying a repeat. It is important to note where the ** begins and ends and if there is another repeat within, that repeat is also to be worked. The final stitches of a row or round might be different from the repeats. Your repeat might note "repeat from ** xx number of times to last 6 stitches" (for example). Then you would finish the row or round in the manner specified. Or it might say, "on last repeat work ..." and give different instructions for the final repeat.


Asterisks are typically used to denote multiplication. In many computer programming languages, double asterisks are used to show exponents. 9*8 = 9 times 8 9**8 = 9 to the power of 8 (98)
