說明：

設計『廣播』物件，傳遞指令給所屬陣列物件。
Client 主程式中，建立 3 個 Soldier 物件，並使其向連隊報到。
- 接著向連隊成員下達命令。
- 各 Soldier 物件接到指令後，進行動作。

// Client.cpp

#include "Client.h"

int Client::main(int argc, const char ** argv)

{

this->myPlatoon.reportToPlatoon(new Soldier("001", "John"));

this->myPlatoon.reportToPlatoon(new Soldier("002", "Fred"));

this->myPlatoon.reportToPlatoon(new Soldier("003", "Richard"));

this->myPlatoon.sendOrder("Get your gears!");

this->myPlatoon.sendOrder("Give me 30 push-ups!");

}
