c++ 实现狼人游戏

更多技术博客 http://vilins.top/题目Task实现一个简单的“狼人游戏”通知机制Details角色有村民狼人预言家女巫猎人Uninitialized只用于默认构造函数法官呼叫“狼人/预言家/女巫/猎人”相应角色进行回答法官呼叫“村民”全体角色回答HintsobjA.on(objB)表示将objB作为objA的监听者事件订阅者知识点观察者模式类与类的关系关联C enum类静态变量One more step将构造函数和初始化操作Player();和void init(std::string name, Role role);分离出来有何优缺点judge.hpp中const Player*能改为const Player吗为什么enum类型Role定义在Player类的public部分有何好处Role为什么定义成enum类型定义成string数组合适吗kMaxCountOfPlayers为什么要作为类静态变量如果类静态变量为double类型还能在类定义中初始化吗代码实现//main.cpp#include judge.hpp #include player.hpp #include cassert #include iostream #include string using std::cin; void RunAllTests() { Judge judge; Player players[Judge::kMaxCountOfPlayers]; std::string name; Player::Role role; for (int i 0; i Judge::kMaxCountOfPlayers; i) { switch (i) { case 0: case 1: case 2: { role Player::Villager; break; } case 3: case 4: case 5: { role Player::Werewolf; break; } case 6: { role Player::Seer; break; } case 7: { role Player::Witch; break; } case 8: { role Player::Hunter; break; } default: assert(false); } cin name; players[i].init(name, role); judge.on(players[i]); } int role_index; cin role_index; judge.call(static_castPlayer::Role(role_index)); } int main() { RunAllTests(); return 0; } /* Two probable tests: input0: Kathy Julie Kenneth Albert William Jack Lisa Carol Harold 2 output0: Calling: Werewolf Albert: Shh...
