operators (std::bitset)
template< std::size_t N > bitset<N> operator&( const bitset<N>& lhs, const bitset<N>& rhs ); | (1) | ? |
|---|---|---|
template< std::size_t N > bitset<N> operator|( const bitset<N>& lhs, const bitset<N>& rhs ); | (2) | ? |
template< std::size_t N > bitset<N> operator^( const bitset<N>& lhs, const bitset<N>& rhs ); | (3) | ? |
在两个位集之间执行二进制和、OR和XOR，lhs和rhs...
1%29bitset<N>包含二进制结果和相应的位对的lhs和rhs...
2%29bitset<N>的对应位对上的二进制或的结果。lhs和rhs...
3%29bitset<N>的对应位对上包含二进制异或的结果。lhs和rhs...
参数
lhs | - | the bitset on the left-hand side of the operator |
|---|---|---|
rhs | - | the bitset on the right-hand side of the operator |
返回值
1%29bitset<N>(lhs) &= rhs
2%29bitset<N>(lhs) |= rhs
3%29bitset<N>(lhs) ^= rhs
例外
(none) | (until C++11) |
|---|---|
noexcept specification: noexcept | (since C++11) |
例
二次
#include <bitset>
#include <iostream>
int main()
{
std::bitset<4> b1("0110");
std::bitset<4> b2("0011");
std::cout << "b1 & b2: " << (b1 & b2) << '\n';
std::cout << "b1 | b2: " << (b1 | b2) << '\n';
std::cout << "b1 ^ b2: " << (b1 ^ b2) << '\n';
}二次
产出：
二次
b1 & b2: 0010
b1 | b2: 0111
b1 ^ b2: 0101二次
