C++編譯錯誤：error: array used as initializer

 在.h裏面直接對數組進行賦值，會報錯error: array used as initializer

class Eth_APP //final : public ethBase
{
public:
    /// @brief Class constructor
    /// @details This constructor initializes the Task parameters and
    /// sets max connection and epoll timeout values.
    /// @param[in] serverTask Pointer to the Ethernet router's IPC server task
    //oemEthRouter();
    Eth_APP();
    /// @brief Class destructor
    ~Eth_APP(void) {};

private:
    //char localIPAddressName[6] = "ens35";

    /// Local IP Address string
    char localIPAddress[INET_ADDRSTRLEN];  //
};

註釋掉char localIPAddressName[6] = "ens35"; 程序正常編譯。
