std::bitset::operators

：位集：：运算符&=，=，^=，~

bitset& operator&=( const bitset& other (1)​
bitset<N>& operator|=( const bitset<N>& other (2)​
bitset<N>& operator^=( const bitset<N>& other (3)​
bitset<N> operator~() const;(4)​

执行二进制和，OR，XOR和NOT。

1%29将位设置为二进制结果，并在相应的位对上设置*this和other...

2%29将位设置为二进制或对应的对位的结果。*this和other...

3%29将位设置为对应的位对上的二进制异或值的结果。*this和other...

4%29返回*this所有位都翻转了%28二进制，而不是%29。

注意&=、=和^=只为相同大小的位集定义N...

参数

other-another bitset

返回值

1-3%29*this

4%29bitset<N>(*this).flip()

例外

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

例

二次

#include <iostream>
#include <string>
#include <bitset>
 
int main()
{
    std::bitset<16> dest;
    std::string pattern_str = "1001";
    std::bitset<16> pattern(pattern_str
 
    for (size_t i = 0, ie = dest.size()/pattern_str.size( i != ie; ++i) {
        dest <<= pattern_str.size(
        dest |= pattern;
    }
    std::cout << dest << '\n';
}
