#include <iostream> using namespace std; int main() { string password, temp; int n, cnt = 0; cin >> password >> n; getchar(); //老哥,请问为啥要用getchar()呢 while(1) { getline(cin, temp); if (temp == "#") break; cnt++; if (cnt <= n && temp == password) { cout << "Welcome in"; break; } else if (cnt <= n && temp != password) { cout << "Wrong password: " << temp << endl; if (cnt == n) { cout << "Account locked"; break; } } } return 0; }
