The type of C++ you are learning is strongly discouraged.
* You are not learning STANDARD C++. Its the Turbo C++, if you
compile on standard C++ compiler like gcc, your program wont even
compile.
* Use of goto statements is strongly discouraged. Use while loops
instead.
* clrscr() and getch() are not a part of standard C++. Even cout
comes under std namespace.
* Also in standard C++, header files wont have ".h" at the end.
You are still a beginner, so it would be easy for you to change. Pls
shift to some nice book. The book you are following now is not teaching
you standard C++.
