C++多層 initializer_list 的傳遞和初始化技巧
class AVD {
public:
AVD(){
std::cout << 1;
}
AVD(std::initializer_list<AVD> Val):Val_(Val){
std::cout << 2;
}
AVD(std::initializer_list<int> Val) {
std::cout << 3;
}
void df() {
std::cout << 4;
}
private:
????std::initializer_list<AVD> Val_;
};
AVD DF({ {1,2},{2,3} });
