There is no sample program for the "coded message" assignment (of course!). The "more image processing" assignment has a sample program called graph4.exe located in the usual sample folder r:\handin\rmanning\examples. Double-click from FileManager to run it.

For assignment #4, choose one of the following. You may want to look over all of them before choosing. (If you don't like choosing, you must pick the first assignment!)

1. The "coded message" program. In this assignment, you will write a program that decodes a hidden message stored as numbers in an array.

2. The "matrix arithmetic" program. An assignment for those who just can't get enough math and engineering! Using arrays to represent matrices, write some functions to perform basic matrix arithmetic. You'll feel like you've extended the C++ language!

3. Some "more image processing." This assignment is like the image processing option for program 3, only the effects are a little more complicated and require the use of arrays to accomplish.
