// Decimal to Binary Conversion (std::bitset)
#include <iostream>
#include <bitset> // Required for std::bitset

int main() {
    // Step 1: Declare variable
    int decimalNum;
    
    // Step 2: Prompt user for input
    std::cout << "Enter a non-negative decimal number: ";
    std::cin >> decimalNum;

    // Step 3: Choose a fixed width for the binary representation
    // Common widths include 8, 16, 32, 64 bits.
    // Ensure the number fits within the chosen width.
    if (decimalNum < 0) {
        std::cout << "Please enter a non-negative number." << std::endl;
        return 1;
    }

    std::cout << "Binary equivalent (8-bit):  " << std::bitset<8>(decimalNum) << std::endl;
    std::cout << "Binary equivalent (16-bit): " << std::bitset<16>(decimalNum) << std::endl;
    std::cout << "Binary equivalent (32-bit): " << std::bitset<32>(decimalNum) << std::endl;
    
    return 0;
