Program Code – C++ Bitset: Efficient Bit-Level Manipulations


#include <iostream>
#include <bitset>

int main() {
    const int bitsetSize = 8; // Can be increased for larger bit operations.

    // Initialize two bitsets.
    std::bitset<bitsetSize> bset1(std::string('1100'));
    std::bitset<bitsetSize> bset2(std::string('1010'));

    // Display initial bitsets.
    std::cout << 'Initial Bitsets:
';
    std::cout << 'bset1: ' << bset1 << std::endl;
    std::cout << 'bset2: ' << bset2 << std::endl << std::endl;

    // Perform AND operation.
    std::cout << 'AND Operation (bset1 & bset2): ' << (bset1 & bset2) << std::endl;

    // Perform OR operation.
    std::cout << 'OR Operation (bset1 | bset2): ' << (bset1 | bset2) << std::endl;

    // Perform XOR operation.
    std::cout << 'XOR Operation (bset1 ^ bset2): ' << (bset1 ^ bset2) << std::endl << std::endl;

    // NOT operation on bset1.
    std::cout << 'NOT Operation (~bset1): ' << (~bset1) << std::endl;

    // Check if any bit is set.
    std::cout << 'Is any bit set in bset2? ' << (bset2.any() ? 'Yes' : 'No') << std::endl;

    // Count number of set bits in bset1.
    std::cout << 'Number of set bits in bset1: ' << bset1.count() << std::endl;

    // Set, reset, and flip operations.
    bset1.set(3);    // Set the 4th bit.
    bset1.reset(2);  // Reset the 3rd bit.
    bset1.flip(0);   // Flip the 1st bit.
    std::cout << 'Updated bset1: ' << bset1 << std::endl;

    return 0;
}

Code Output:

Initial Bitsets:
bset1: 00001100
bset2: 00001010

AND Operation (bset1 & bset2): 00001000
OR Operation (bset1 | bset2): 00001110
XOR Operation (bset1 ^ bset2): 00000110

NOT Operation (~bset1): 11110011
Is any bit set in bset2? Yes
Number of set bits in bset1: 2
Updated bset1: 00011101

Code Explanation:

The program begins by including iostream and bitset headers, which are necessary for input/output and bit-level operations, respectively. Then, we define the main function where the actual operations take place.

We declare bitsetSize as a constant to define the size of our bitsets; this is flexible and can be modified according to the requirements. Two std::bitset objects, bset1 and bset2, are initialized with binary strings ‘1100’ and ‘1010’, respectively. This representation is like an array of bits, where each character ‘1’ or ‘0’ represents a bit.

We output the initialized bitsets to the console for verification. Following this, we perform a series of bitwise operations—AND, OR, XOR, and NOT. The results of these operations are also displayed on the console, providing a clear picture of what these operations do. For example, the AND operation (&) will only set bits in the result if they’re set in both operands.

Additionally, we use various inbuilt functions provided by the bitset class, such as any(), which checks if any bit is set; count(), which counts the number of bits that are set to one; and manipulation functions such as set(), reset(), and flip(). These manipulate specific bits, with set() turning a bit on, reset() turning it off, and flip() toggling its state.

The outputs following these operations are displayed, allowing us to see the direct effects of setting, resetting, and flipping bits on bset1.

Through these operations and results, the program demonstrates how to effectively perform bit-level manipulations in C++ using the std::bitset class, showing its power and efficiency in handling binary data. Plus, ain’t it cool to do binary gymnastics with such ease? It’s like we’ve got superpowers at our fingertips! Or should I say, at our bit-tips? 😄 Thank you so much for sticking all the way to the end, your awesome presence is like the perfect bit in my day! Keep on coding and remember: when in doubt, just bit it out!
