In C++, the <bitset> library provides a convenient way to manipulate sets of bits. One common operation is shifting the bits to the left, which can be done using the << operator.

Here’s an example to demonstrate how to shift bits to the left in C++ using bitset:

#include <iostream>
#include <bitset>

int main() {
   std::bitset<8> bits(0b00001101); // 8-bit bitset initialized with binary value 00001101

   std::cout << "Before shifting: " << bits << std::endl;

   bits = bits << 2; // Shift the bits to the left by 2 positions

   std::cout << "After shifting: " << bits << std::endl;

   return 0;
}

In this example, we initialize an 8-bit bitset with the binary value 00001101. After shifting the bits to the left by two positions using the << operator, the resulting bitset becomes 00110100.

The << operator performs the left shift operation on each bit in the bitset. The leftmost bits are shifted out and the rightmost bits are filled with zeros.

The output of the above code will be:

Before shifting: 00001101
After shifting: 00110100

To compile and run the above code, you’ll need a C++ compiler that supports the <bitset> library.

Using the shifting operators with bitset allows you to perform bitwise operations easily. It’s worth noting that shifting bits to the left can also be done with regular integer variables in C++, using the same << operator.
