Homework

Do the Self Review exercises at the end of Chapter 2 (2.1 through 2.13) and check your own work. Do not hand in the answers.

The following assignment is due the day of Class_3.

Write C++ programs to answer each of the following exercises:

Exercises 2.15, 2.20, 2.26, 2.27, 2.47
Exercises 3.11, 3.20

When all of the programs compile and run correctly, put all the source files (and only the source files) into a directory, tar the directory and e-mail it to your instructor. Be sure you name the tar file and attach it to your e-mail message as described in Submitting a Project.

Use the following code as a model for the block of comments you are to put at the beginning of each source file:

     /* exercise_2.15.cc
      *
      *    This program prints ... <tell what the program does>
      *
      *    <put your name here>
      *    <put the date here>
      *
      */
