This not so useful tip tells you how to declare a reference for a two dimensional array without needing to use typecasting.
int x[1][20];
int (*p)[20] = x;
Here p has become a reference to x.
Usually in most cases, we use:
int** p = (int**) x;
So, this tip gives you a hint about how to declare another reference for x without typecasting.
