十月抽奖代码

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

using namespace std;

int main()
{
    int min = 1, max = 20;
    random_device seed; 
    ranlux48 engine(seed());
    uniform_int_distribution<> distrib(min, max);
    int random = distrib(engine);
    cout << random << endl;
    return 0;
}

帮助@源泉同学

注意min和max改成同学编号
