遇到的問題： (題意請描述清楚) 各位大哥不好意思，小弟又有問題想請教在昨天把C++無法標頭檔的問題解決後，小弟我又嘗試把標頭檔分成函式原型、函式定義 .cpp檔的每個成員函式加上" (類別):: " 之後，卻編譯失敗試了3、4個鐘頭，仍然不得其解，愈試愈灰心= = 煩請各位大大指導，謝謝！希望得到的正確結果：也是只求能順利編譯程式跑出來的錯誤結果：錯誤訊息如下： [Linker error] undefined reference to `tenfive::tenfive()' [Linker error] undefined reference to `tenfive::settozero()' [Linker error] undefined reference to `tenfive::DealCard1()' [Linker error] undefined reference to `tenfive::DealCard2()' [Linker error] undefined reference to `tenfive::pointSum()' [Linker error] undefined reference to `tenfive::DealOrEnd()' ld returned 1 exit status 開發平台： (例: VC++ or gcc/g++ or Dev-C++, Windows or Linux) Dev C++ 有問題的code： (請善用置底文標色功能) 函式原型： //tenfive.h class tenfive { public: void DealCard1(); void DealCard2(); void pointSum(); void DealOrEnd(); void WinOrLose(); void DealAgain(); void settozero(); private: int card2; int NoofCard; int point1; float point2; float allpoint; int suit1; int suit2; }; 函式定義： //tenfive.cpp #include <iostream> using std::cin; using std::cout; using std::endl; #include <cstdlib> using std::rand; using std::srand; #include "tenfive.h" void tenfive::DealCard1() { srand( time ( 0 )); suit1 = 0; point1 = 8 + rand()%3; suit1 = rand()%4; } void tenfive::DealCard2() { srand( time ( 0 )); point2 = 0; suit2 = 0; card2 = 1 + rand()%54; NoofCard += 1; point2 = 1 + card2%13; suit2 = card2 / 13; switch ( suit2 ) { case 4: cout << "You get joker." << endl; break; case 3: cout << "You get <^>" << point2 << "." << endl; break; case 2: cout << "You get []" << point2 << "." << endl; break; case 1: cout << "You get v" << point2 << "." << endl; break; case 0: cout << "You get A" << point2 << "." << endl; break; } } void tenfive::pointSum() { if ( point2 <= 13 && point2 >= 11 ) allpoint += 0.5; else if ( suit2 == 4 ) { if ( (allpoint + 10) > 10.5 ) allpoint += 0.5; else allpoint += 10; } else allpoint += point2; cout << "Your total point:" << setw(4) << allpoint << endl; } void tenfive::DealOrEnd() { if ( allpoint >= 10.5 ) WinOrLose(); else if ( NoofCard >= 5 ) cout << "You win! (You get 5 cards.)" << endl; else DealAgain(); } void tenfive::WinOrLose() { cout << "Banker's point: " << setw(4) << point1 << endl; if ( allpoint > 10.5 || allpoint <= point1 ) cout << "You lose!" << endl; else if ( allpoint == 10.5 ) cout << "You win! 10.5!" << endl; else cout << "You win!" << endl; } void tenfive::DealAgain() { char deal; cout << "Enter \"y\" to deal again, enter \"n\" to start the gamble. "; cin >> deal; cout << "\n"; switch ( deal ) { case 'Y': case 'y': DealCard2(); pointSum(); DealOrEnd(); break; default: WinOrLose(); } } void tenfive::settozero() { NoofCard = 0; allpoint = 0; } 補充說明：順便問一樣大大們寫程式的習慣，應該先寫函式原型、函式定義還是主程式，或者是同時進行？另外，有沒有什麼專門教debug的網站，不然我每次看到錯誤訊息，也不知道如何下手才好…〒△〒 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.115.206.28
