C++ <bitset> - operator>> Function

The C++ <bitset> operator>> function is used to extract up to N bits from basic_istream (is) and store into another bitset rhs.

Syntax

C++98
C++11

template<class charT, class traits, size_t N>
  basic_istream<charT, traits>&
    operator>> (basic_istream<charT,traits>& is, const bitset<N>& rhs);

template<class charT, class traits, size_t N>
  basic_istream<charT, traits>&
    operator>> (basic_ostream<charT, traits>& is, const bitset<N>& rhs);

Parameters

`is`	The basic_istream object from which the bitset object is extracted.
`rhs`	Specify right-hand side bitset object.

Return Value

Returns the character stream is.

Exception

In case of exception, all object remains in valid state.

Example:

The example below shows the usage of operator>> function.

#include <iostream>
#include <bitset>
#include <sstream>
using namespace std;
 
int main (){
  string s = "111000";
  istringstream stream(s);
  bitset<2> bset1;
  bitset<4> bset2;

  //extracting first 2 bits into bset1
  stream >> bset1;
  cout<<"bset1 = "<<bset1;

  //extracting next 4 bits into bset2
  stream >> bset2;
  cout<<"\nbset2 = "<<bset2;

  return 0;
}

The output of the above code will be:

bset1 = 11
bset2 = 1000
