For me it was the practical understanding. I understood the concept of a pointer, but I wasn't confident in writing code that used that used them or (more importantly) reading code. I would see an asterisk, multiple asterisks, or ampersands, and would get confused with the code. I do think some of the issues I encountered had to do with the notation of pointers. The asterisk serving as a symbol to both declare a pointer variable and dereference one.
