在C中初始化hash_map++

你会得到这样的东西(我还没有添加向量,但这增加了初始化的额外{}级别)。我只是想给你一个主意

#include <string>
#include <map>

enum class Piece
{
    Pawn,
    Bishop,
    Rook
};

enum class Color
{
    Black,
    White
};

struct Direction
{
    int horizontal;
    int vertical;
};

struct Movement
{
    Color color;
    Direction direction;
};

int main()
{
    std::map<Piece,Movement> moves{
        { Piece::Pawn, // <- key of your map, e.g. a Piece enum value
         { 
            Color::White,   // First member of Movement, e.g. Color enum value
            {0,1}           // Second member of Movement, Direction {0 horizontal, 1 vertical)
         }
        },
        { Piece::Bishop, { Color::Black, {8,8} } }
    };

    return 0;
}
