172 | 172 | * The size of the array called `str[]` is set by an integer constant, and this value is needed twice more in the program where it is accessible as `size(str)`, a compile-time value. An alternative way would be to use a constant or macro at each point the value is needed, and this is the only way to avoid repeated *magic constants* in older versions of C++ which did not provide `std::size()`. |
