To start with, let’s create two bitsets, bitsetA and bitsetB, with some random values:

std::bitset<8> bitsetA("10101010");
std::bitset<8> bitsetB("11001100");

Now, we want to find the union of these two bitsets. To do this, we can use the bitwise OR operator (|). This operator performs a logical OR operation between the bits of the operands, resulting in a new bitset with the bits set to 1 where either of the corresponding bits in the original bitsets is 1.

std::bitset<8> unionBitset = bitsetA | bitsetB;

Here, unionBitset will contain the union of bitsetA and bitsetB.

To verify the result, we can print the binary representation of the unionBitset:

std::cout << unionBitset.to_string() << std::endl;

This will output 11101110, which is the binary representation of the union of bitsetA and bitsetB.

And that’s it! You have successfully found the union of two bitsets in C++. You can use this approach with any size of bitsets, as long as they have the same length.
