std::bitset::size

STD：：位集：：大小

std::size_t size() const;​(until C++11)
constexpr std::size_t size(​(since C++11) (until C++14)
constexpr std::size_t size() const;​(since C++14)

返回位集可以容纳的位数。

参数

%280%29

返回值

位集可以容纳的位数，即模板参数N...

例外

(none)(until C++11)
noexcept specification: noexcept(since C++11)

另见

countreturns the number of bits set to true (public member function)
