operator>> (<bitset>)

读取位字符串到 bitset。

template<class CharType, class Traits, size_t Bits> 
   basic_istream<CharType, Traits>& operator>> ( 
      basic_istream<CharType, Traits>& _Istr,
      bitset<N>& _Right 
   );

参数

• _Istr
  输入到要插入的内容为 bitset 的字符串。

• _Right
  接收输入流中的位的 bitset。

返回值

模板函数返回字符串 _Istr。

备注

模板函数。bitset _Right 重载 运算符>> 值存储 bitset (str)，其中 str 为CharType类型，basic_string<特征，allocator<CharType> >从 _Istr提取的**&** 对象。

模板函数从 _Istr 提取元素并将这些类插入 bitset 之前：

• 所有元素 bitset 位输入流中提取和存储。

• bitset 填满的输入流的位。

• 不是 0 和 1. 中输入元素时。

示例

#include <bitset>
#include <iostream>
#include <string>

using namespace std;
int main()
{

   bitset<5> b1;
   cout << "Enter string of (0 or 1) bits for input into bitset<5>.\n"
        << "Try bit string of length less than or equal to 5,\n"
        << " (for example: 10110): ";
   cin >>  b1;

   cout << "The ordered set of bits entered from the "
        << "keyboard\n has been input into bitset<5> b1 as: ( "
        << b1 << " )" << endl;

   // Truncation due to longer string of bits than length of bitset
   bitset<2> b3;
   cout << "Enter string of bits (0 or 1) for input into bitset<2>.\n"
        << " Try bit string of length greater than 2,\n"
        << " (for example: 1011): ";
   cin >>  b3;

   cout << "The ordered set of bits entered from the "
        << "keyboard\n has been input into bitset<2> b3 as: ( "
        << b3 << " )" << endl;

   // Flushing the input stream
   char buf[100];
   cin.getline(&buf[0], 99);

   // Truncation with non-bit value
   bitset<5> b2;
   cout << "Enter a string for input into  bitset<5>.\n"
        << " that contains a character than is NOT a 0 or a 1,\n "
        << " (for example: 10k01): ";
   cin >>  b2;

   cout << "The string entered from the keyboard\n"
        << " has been input into bitset<5> b2 as: ( "
        << b2 << " )" << endl;
}
