或者使用header和std：：vector，std：：generate（没有原始循环）。同样，当你写代码时，写一些可读的小函数。为了得到唯一的随机数，随机生成器需要被播种。

#include <algorithm>
#include <iostream>
#include <random>
#include <vector>

int generate_random_number()
{
    // only initialize the generator and distribution once (static)
    // and initialize the generator from a random source (device)
    static std::mt19937 generator(std::random_device{}());
    static std::uniform_int_distribution<int> distribution{ 1,10 };
    return distribution(generator);
}

// overload stream output for vector, so we can use vectors in std::cout
std::ostream& operator<<(std::ostream& os, const std::vector<int>& values)
{
    bool comma{ false };
    
    os << "[";
    for (const int value : values)
    {
        if (comma) os << ", ";
        os << value;
        comma = true;
    }
    os << "]";

    return os;
}

// helper function to create an array of given size
std::vector<int> create_random_array(const std::size_t size)
{
    std::vector<int> values(size); // create and allocate memory for an array of size ints
    std::generate(values.begin(), values.end(), generate_random_number); // fill each value in the array with a value from the function call to generate_random_number
    return values;
}

int main()
{
    std::size_t count;
    std::cout << "how many random numbers ? : ";
    std::cin >> count;

    auto array1 = create_random_array(count);
    std::cout << array1 << "\n";

    auto array2 = create_random_array(count);
    std::cout << array2 << "\n";

    return 0;
}
