std::bitset::reset

STD：：位集：：重置

bitset& reset((1)​
bitset<N>& reset( size_t pos (2)​

将位设置为false...

1%29将所有位设置为false

2%29设置位在位置pos到false...

参数

pos-the position of the bit to set

返回值

*this...

例外

1%29

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

2%29投std::out_of_range如果pos不对应于位集中的有效位置。

例

二次

#include <iostream>
#include <bitset>
 
int main()
{
    std::bitset<8> b(42
    std::cout << "Bitset is         " << b << '\n';
    b.reset(1
    std::cout << "After b.reset(1): " << b << '\n';
    b.reset(
    std::cout << "After b.reset():  " << b << '\n';
}

二次

产出：

二次

Bitset is         00101010
After b.reset(1): 00101000
After b.reset():  00000000

二次

另见

setsets bits to true or given value (public member function)
fliptoggles the values of bits (public member function)
