如何在C++中创建随机字母数字字符串？

#include<iostream>
#include<random>
#include<string>
#include <ctime>

std::string generate_random_alphanumeric_string(int length) {
    std::string alphanumeric_chars = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
    std::string random_string;
    std::default_random_engine generator(static_cast<unsigned int>(std::time(0)));
    std::uniform_int_distribution<size_t> distribution(0, alphanumeric_chars.size() - 1);

    for (int i = 0; i< length; ++i) {
        random_string += alphanumeric_chars[distribution(generator)];
    }

    return random_string;
}

int main() {
    int length = 10;
    std::string random_string = generate_random_alphanumeric_string(length);
    std::cout << "Random alphanumeric string: "<< random_string<< std::endl;
    return 0;
}
