下列程式執行後，執行結果為何？ #include "stdafx.h" #include <iostream> #include <string> using namespace std; class SayHi { public: SayHi(string name) {setHiName(name);} void setHiName(string name) { hiName=name; } string getHiName() {return hiName;} void displayHiName() {cout << getHiName() << "!" << endl;} private: string hiName ; }; int _tmain(int argc , _TCHAR* argv[]) { SayHi hello1("Lunar"); SayHi hello2("Iris"); cout << "Say1: " << hello1.getHiName() << "\nSay2: "<< hello2.getHiName() << endl ; return 0 ; }
