Dear my friends... I am trying to learn and practice GNU C++. I start with this very simple program: ===== #include <iostream.h> #include <ctype.h> #include <stdlib.h> class menu { public: int pilihan; void tampil(); }; int main(){ menu * m = new menu(); m->tampil(); return 0; } void menu::tampil(){ for (;;){ cout << "Menu : (S)amba (P)ostfix (B)ind (Q)uit\n"; cin >> pilihan; switch ( toupper(pilihan) ){ case 'S': cout << "You are administrating Samba Server" << endl; break; case 'P': cout << "You are administrating Postfix Server" << endl; break; case 'B': cout << "You are administrating BIND Server" << endl; break; cout << "You selected Quit. Good bye!" << endl; case 'Q': exit(0); default: cout << "***No such command!***" << endl; break; } } } ===== I compiled it successfully, as below : ===== patrixlinux@patrix:~/arsip/proyek/gcc/1> ls liss liss.cpp liss.cpp~ patrixlinux@patrix:~/arsip/proyek/gcc/1> g++ -o liss liss.cpp In file included from /usr/include/g++/backward/iostream.h:31, from liss.cpp:1: /usr/include/g++/backward/backward_warning.h:32:2: warning: #warning This file includes at least one deprecated or antiquated header. Please consider using one of the 32 headers found in section 17.4.1.2 of the C++ standard. Examples include substituting the <X> header for the <X.h> header for C++ includes, or <sstream> instead of the deprecated header <strstream.h>. To disable this warning use -Wno-deprecated. patrixlinux@patrix:~/arsip/proyek/gcc/1> ./liss Menu : (S)amba (P)ostfix (B)ind (Q)uit s ==== But the problem is my program does not run as expected. It does like this below without ending: ==== Menu : (S)amba (P)ostfix (B)ind (Q)uit ***No such command!*** Menu : (S)amba (P)ostfix (B)ind (Q)uit ***No such command!*** Menu : (S)amba (P)ostfix (B)ind (Q)uit ***No such command!*** Menu : (S)amba (P)ostfix (B)ind (Q)uit ***No such command!*** Menu : (S)amba (P)ostfix (B)ind (Q)uit ***No such command!*** Menu : (S)amba (P)ostfix (B)ind (Q)uit ***No such command!*** ==== I aborted with <control>-<C>. what's wrong with my code? Lookslike my code does not receive the pressed key properly. Please help. Thank you very much in advance. __________________________________ Do you Yahoo!? Yahoo!
