---

Description

The C++ function std::bitset::operator<<= performs bitwise left SHIFT operation on current bitset object.

Declaration

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

C++98

bitset& operator<<= (size_t pos);

C++11

bitset& operator<<= (size_t pos) noexcept;

Parameters

pos − Number of bits to be shifted.

Return value

Returns this pointer.

Exceptions

This member function never throws exception.

Example

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

#include <iostream>
#include <bitset>

using namespace std;

int main(void) {
   bitset<4> b("0001");

   b <<= 1;

   cout << b << endl;

   return 0;
}

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