- With the * in your first datastuff declaration, you are declaring a two dimensional array of _pointers_ to double (ie an array of memory addresses). You don't want that (unless you are doing a lot of pointing) - you just want an array of doubles. Now under ...

If we do not pass the length, the function has no standard means of knowing where the array ends. We will also examine how to create jagged arrays in C, although they are infrequently used. A jagged array is a two-dimensional array where each row may have a different number of columns...
