成员变量是数组，通过初始化列表来初始化
需求 今天编译是报错: warning: list-initializer for non-class type must not be parenthesized, 报错的地方是对类中包含的成员变量是一个数组，然后使用了列表初始化。 解决 其实这个报错提示已经说的很清楚了，对非类使用了列表初始化并且加了括号。所以解决的方法也很简单，这种数组成员变量初始化使用列表初始化时，不要加括号就 ok 了。 class Sn74cbtlv3253 { //using FuncVoidVoid = void (*)(void); using FuncVoidBool = void (*)(bool); public: enum Index { kIndex1 = 0, kIndex2, kIndex3, kIndex4, }; public: Sn74cbtlv3253(FuncVoidBool s0, FuncVoidBool s1, FuncVoidBool oe) : s0_(s0), s1_(s1), oe_(oe) {}; void Switch(Index index); void Disconnect(); private: FuncVoidBool s0_; FuncVoidBool s1_; FuncVoidBool oe_; }; class Channel { public: enum ChannelIndex { kChannel1 = 0, kChannel2, kChannel3, kChannel4, kChannel5, kChannel6, kChannel7, kChannel8, kChannel9, kChannel10, kChannel11, kChannel12, }; public: Channel(); void Switch(ChannelIndex index); void Disconnect(); private: Sn74cbtlv3253 sn74cbtlv3253_[6][2]; }; Channel::Channel() : sn74cbtlv3253_{ {{Chip1S0PinControl, Chip1S1PinControl, Chip1En1PinControl}, {Chip1S0PinControl, Chip1S1PinControl, Chip1En2PinControl}}, {{Chip2S0PinControl, Chip2S1PinControl, Chip2En1PinControl}, {Chip2S0PinControl, Chip2S1PinControl, Chip2En2PinControl}}, {{Chip3S0PinControl, Chip3S1PinControl, Chip3En1PinControl}, {Chip3S0PinControl, Chip3S1PinControl, Chip3En2PinControl}}, {{Chip4S0PinControl, Chip4S1PinControl, Chip4En1PinControl}, {Chip4S0PinControl, Chip4S1PinControl, Chip4En2PinControl}}, {{Chip5S0PinControl, Chip5S1PinControl, Chip5En1PinControl}, {Chip5S0PinControl, Chip5S1PinControl, Chip5En2PinControl}}, {{Chip6S0PinControl, Chip6S1PinControl, Chip6En1PinControl}, {Chip6S0PinControl, Chip6S1PinControl, Chip6En2PinControl}}, } { Disconnect(); } 参考 list initializer for non class type must not be parenthesized werror...
