bitset<N> operator<<( size_t pos ) const;
(1)
bitset<N>& operator<<=( size_t pos );
(2)
bitset<N> operator>>( size_t pos ) const;
(3)
bitset<N>& operator>>=( size_t pos );
(4)

Performs binary shift left and binary shift right. Zeroes are shifted in.

1-2) Performs binary shift left. The (2) version is destructive, i.e. performs the shift to the current object.

3-4) Performs binary shift right. The (4) version is destructive, i.e. performs the shift to the current object.

[edit] Parameters

pos - number of positions to shift the bits

[edit] Return value

1,3) new bitset object containing the shifted bits

2,4) *this

[edit] Example

#include <iostream>
#include <bitset>
 
int main()
{
    std::bitset<8> b("01110010");
    std::cout << "initial value: " << b << '\n';
 
    while (b.any()) {
        while (!b.test(0)) {
            b >>= 1;
        }
        std::cout << b << '\n';
        b >>= 1;
    }
}

Output:

initial value: 01110010
00111001
00000111
00000011
00000001
