Hey,
I know that declaring a enum is done like this for examplewin_directions_t is the enum type(if i understood the tutorial well), but what if the enum doest have a type and is declared like thisCode:enum wind_directions_t {NO_WIND, NORTH_WIND, SOUTH_WIND, EAST_WIND, WEST_WIND};Whats the difference about having a type and not?Code:enum {NO_WIND, NORTH_WIND, SOUTH_WIND, EAST_WIND, WEST_WIND};
Well, you just won't be able to declare a variable of that type. In some cases, such as when the enumerations are being used as bitmasks, it really isn't useful to name the enum anyway, since the type can't be used directly in bit manipulation (without a cast to int).
Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
Thanks for clearing that up for me
