C++用户定义的随机数生成器

Question

我在生成用户定义范围内的 10 个随机数时遇到了一些问题。

到目前为止我有这个:

int minimum, maximum, randNum;

cout << "Hello, please insert the smallest number for your range of random numbers" << endl;
cin >> minimum;
cout << "Please insert your largest number for your range of random numbers" << endl;
cin >> maximum;

srand (time(NULL));
randNum = rand()%(maximum-minimum)+minimum;

不太确定从这里去哪里。感谢任何帮助，谢谢!

给你:

#include <iostream>
#include <random>

int main() {
    int minimum, maximum;
    std::cin >> minimum >> maximum;

    // Create a random number generator
    std::random_device rd;
    std::mt19937 gen(rd());

    // We want random numbers within [minimum, maximum]
    std::uniform_int_distribution<> dis(minimum, maximum);

    // Print 10 random numbers    
    for (int i=0; i<10; ++i)
        std::cout << dis(gen) << "\n";
}
