尝试将C++二进制数组转换为十六进制，然后打印结果

#include <iostream>
#include <iomanip>

void printHexFromBinaryArray(const unsigned char* binaryArray, int size) {
    for (int i = 0; i < size; i++) {
        unsigned char binaryElement = binaryArray[i];
        unsigned char lowNibble = binaryElement & 0xF;
        unsigned char highNibble = (binaryElement >> 4) & 0xF;

        std::cout << std::hex << std::setw(2) << std::setfill('0') << static_cast<int>(highNibble);
        std::cout << std::hex << std::setw(2) << std::setfill('0') << static_cast<int>(lowNibble) << " ";
    }
    std::cout << std::endl;
}

int main() {
    unsigned char binaryArray[] = {0b01010101, 0b11001100, 0b00110011};
    int size = sizeof(binaryArray) / sizeof(binaryArray[0]);

    printHexFromBinaryArray(binaryArray, size);

    return 0;
}
