Description

The C++ function std::bitset::operator>> inserts bitset x to the character stream os.

Declaration

Following is the declaration for std::bitset::operator>> function form std::bitset header.

C++98

template<class charT, class traits, size_t N>
basic_ostream<charT, traits>&
operator<< (basic_ostream<charT,traits>& os, const bitset<N>& x);

C++11

template<class charT, class traits, size_t N>
basic_ostream<charT, traits>&
operator<< (basic_ostream<charT,traits>& os, const bitset<N>& x);

Parameters

• os − Character stream to write to.

• x − The bitset to be written.

Return value

Returns the character stream that was operated i.e. os.

Exceptions

If exception occurs all object remains in valid state.

Example

The following example shows the usage of std::bitset::operator>> function.

#include <iostream>
#include <bitset>
#include <sstream>

using namespace std;

int main(void) {

   string s = "101010";
   istringstream stream(s);
   bitset<2> b1;
   bitset<6> b2;

   /* Store first 2 bits */
   stream >> b1;
   cout << "b1 = " << b1 << endl;

   /* Stores next 4 bits */
   stream >> b2;
   cout << "b2 = " << b2 << endl;

   return 0;
}

Let us compile and run the above program, this will produce the following result −

b1 = 10
b2 = 001010
