What does this notation mean in C?
c, pointers
Solution
After the assignment, `**d` is the same as `*w`. `d` is a pointer to a pointer to an integer; the pointer to an integer that it points to is `w`. So `*d` is `w`, and `**d` is `*w`.
Problem
``` int *w; int **d; d = &w; ``` What does the **d store exactly?
