This requires you to read, understand, and tell in simple
English what several substring programs do both on particular
input and on inputs in general.
Hint: You can try running the programs after making
your initial guess on what they do on the particular input.
However, note that you also have to tell what they do in
general, which can't be answered just by running the
program; you'll need to understand the program to answer
that!
Do Biermann, Ch. 2, p. 58, #2:
This requires you to design, write,
compile, and test (and debug, if necessary) a Pascal program
that uses the substring function.
You should turn in the following, all stapled in the upper-left corner:
Cover page with your name (clearly printed), lab number, date.
For the first set of problems, your handwritten answers.
For the second problem: Your program + 2 different sample runs
If your program doesn't work by the due date, then turn in a bug report.
