Take-home
midterm handed out today, Oct 11 (day 20) due the
following Wednesday. Through
If/Else.
I will be basing "6-week grades" on the HW I have received today
Oct 11 at the beginning of class.
Beginning code for problem 9 Midtermfile.htm
HW Day 20, Due Fri
Day 21
Textbook p.
318,
A. (Another loop) Write a program
which gets character input from the keyboard, and prints *? as long as
the input is not "y". When it gets "y", it prints !! and
quits. (Do this with batch input first. Then after it
works, try it with interactive I/O. Any new difficulties?) Input abcy, output *?*?*?!!. Interactive,
things will be interspersed. EXTRA CREDI:T: Count how many
characters are input before the y, output that number last (for
abcy, 3). Do it WITHOUT using the X register.
Textbook p.
318, #15 (Write a "for" loop. You may use "global" variables
and direct
addressing, or "local" variables and stack-relative addressing. )
Think about Program 5 (not assigned yet)
D next time).
Think about how to multiply a number
by a 4-bit number, in
binary. Come in with a
pseudocode or flowcharted algorithm. (With or without a loop, your
choice.)
= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =
= = = = = = =
Notes: Homework questions?
Loops: While, Do while, For Handout.
The loop examples from
the text
p. 247, Fig. 6.10, while.
Start problem A for HW.
p. 249, Fig 6.11, do while.
p. 251, Fig 6.12, for (with stack)
How to multiply whole
numbers? (We will program this.)
