Writing a Large Program

1. Divide the problem into smaller and smaller
   portions until each portion can be easily solved.
   
2. Perform the basic problem solving technique on
   the previous slide for each sub-problem one at a
   time.
3. Put the components together one at a time and
   test them one at a time.
4. Perform a final test .
