Why does this work? Illogical array access
In simplistic terms, the access of an array element in C (and in C++, when [] isn't overloaded) is as follows:
x[i] = *(x + i)So, with this and a little bit of arithmetic...
foo[i][bar]= (foo[i])[bar]= (*(foo + i))[bar]= *((*(foo + i)) + bar)= *(bar + (*(foo + i)))= bar[*(foo + i)]= bar[foo[i]]Don't use this "fact" though. As you've seen, it makes the code unreadable, and unreadable code is unmaintainable.
