如何打印十六进制字节数组- c++ [复制]

#include <iostream>
#include <iomanip>
#include <sstream>
#include <vector>

std::string ByteArrayToHexString(const std::vector<unsigned char>& byteArray) {
    std::stringstream ss;
    for (size_t i = 0; i < byteArray.size(); ++i) {
        ss << std::hex << std::setw(2) << std::setfill('0') << static_cast<int>(byteArray[i]);
        if (i < byteArray.size() - 1) {
            ss << " ";
        }
    }
    return ss.str();
}

int main() {
    std::vector<unsigned char> byteArray = {0x1A, 0x2B, 0x3C, 0x4D, 0x5E, 0x6F};
    std::string hexString = ByteArrayToHexString(byteArray);
    std::cout << "Hexadecimal representation of the byte array: " << hexString << std::endl;
    return 0;
}
