【每日话题】如何用各种编程语言实现每日话题抽奖机制？

string s[MAXN]; int tot(0); while( cin >> s[tot] ) ++tot; int c = rand() % tot + 1; cout << "本期幸运牛友： @"<< s[c] << endl; cout << "牛币奖励已发放至账户，请注意查收~" << endl; cout << "-------------------------" << endl; cout << "每日话题已更新！" << endl; cout << "欢迎大家踊跃参与~~" << endl; cout << "传送门：" << endl; cout << "<a href=\"https://ac.nowcoder.com/discuss/253100\"><\\a>" << endl;

#include<bits/stdc++.h> using namespace std; string username[2333]; int main(){     string x;int e=0;     while(cin>>x){         username[++e]=x;     }     for(int i=1;i<=e;++i){         if(username[i]=="ThinkofBlank"){             cout<<"本次中奖楼数"<<i;         }     }     return 0; }

map <int, string> mp; string s; int random (int l, int r) {  return rand() * rand() % (l+r-1); } int main () {  srand (time (0));  int i = 0;  while (cin >> s) {   mp[++i] = s;  }  int qaq = random (1, i);  cout << qaq << endl;  return 0; }
