C++ <bitset> - operator<< Function

The C++ bitset::operator<< function is used to perform bitwise left SHIFT operation on the given bitset.

Syntax

C++98
C++11

bitset operator<<(size_t pos) const;

bitset operator<<(size_t pos) const noexcept;

Parameters

pos Specify number of bit locations to be shifted.

Return Value

Returns new bitset object which contains shifted bits.

Exception

Never throws exceptions.

Example:

In the example below, the bitset::operator<< function is used to perform bitwise left SHIFT operation on the given bitset.

#include <iostream>
#include <bitset>
using namespace std;
 
int main (){
  bitset<4> bset("1001");

  cout<<"bset is: "<<bset;

  //performing bitwise left shift operation using bset
  cout<<"\n(bset<<1): "<<(bset<<1);
  cout<<"\n(bset<<2): "<<(bset<<2);

  return 0;
}

The output of the above code will be:

bset is: 1001
(bset<<1): 0010
(bset<<2): 0100
