Can't seem to use left or right shift

I was just playing around a bit(no pun intended) with std::bitset in c++ and I ran in to a problem.

I can use OR, AND and EXCLUSIVE OR just fine, but when I try to do shift operations using >> and << I get an error saying

Error: no operator "<<" matches these operands

The code I have looks like this:

#include <iostream>
#include <bitset>

using namespace std;

int main()
{
    bitset<8> test = 0x05;
    bitset<8> test2 = 0x00;
    bitset<8> lshift = test << test2;
    cout<<lshift<<endl;
    system("PAUSE");
    return 0;
}
Solution

  • There is simply no such operator defined for shifting a std::bitset by another std::bitset. The only shifting operators are defined for arguments of type std::size_t, see for example http://en.cppreference.com/w/cpp/utility/bitset/operator_ltltgtgt.
