problem_points = ceil[ exp(*problem_difficulty) ]

Exercises

1. Section 7.10, page 163, exercise 4 (*1.5)
   1. This program should accept command lines such as

      "cat chap7_num4.cpp chap7_num14.cpp"

   2. The program's result should sent to a file and consist of each line of chap7_num4.cpp followed by each line of chap7_num14.cpp in the command line example given
2. Section 7.10, page 163, exercise 7 (*2.5) - solve this with two separate programs:
   1. (7a) first solve "Write a funtction for entering new words into a tree Tnodes. Write a function to write out a tree of Tnodes. Write a function to write out a tree of Tnodes with the words in alphabetical order.
   2. (7b) next solve "Modify Tnode so that it stores (only) a pointer to an arbitrarily long word stored as an array of characters on free store using new. Modify the functions to use the new definiton of Tnode.
3. Section 7.10, page 164, exercise 14 (*1)
