const int a = 1; // read as "a is an integer which is constant" int const a = 1; // read as "a is a constant integer" Both are the same thing. Therefore: a = 2; // Can't do because a is constant The reading backwards trick especially comes in handy when you're dealing with more complex declarations such as: const char *s; // read as "s is a pointer to a char that is constant" char c; cha..
