Design & Implementation Hints

  1. Design your user interface. List in order exactly each of the things that the computer displays and what the user types in.
  2. Use graph paper to design your graphics. You need to be careful about placing individual marks on the screen.
  3. Design your algorithm so that it proceeds in the order given in your description of the user interface.
  4. If some action or sequence of actions is performed in several different places in your algorithm, consider turning that action or sequence of actions into a function and invoking this function whenever you need to perform that action or action sequence.
  5. If some action or sequence of actions is performed several times all at once in the same place in your algorithm, then consider writing the action once and inclosing it in a loop structure.
  6. Remember that you can combine functions and loops.
  7. Define each of the functions and other objects using the same classes, names, and types as in the instructions.
  8. Copy the algorithm given in the instructions into your source code file, and turn the algorithm description into comments
  9. Fill in the code needed to do each part of the algorithm after its comment.
  10. Do not have more than twenty or fifty lines in a single function.
