9. Present an example of a logic bug using pseudocode and explain your

Temperature = 70

Will work because if temperature is higher than 69 degrees and
temperature is lower than 100 degrees windows will open.
2. Gentlemen, after reading your advise I had run the code in C++,

mistakenly use the "AND" && operator instead of the "OR" || operator
which I found the latter to run a loop which I couldn't end, not even
with a ctrl-c, and had to push the power button in to turn off my
computer (please keep that in mind). Also found that the temperatures
reflected would better reflect opening the windows and not closing
them.
Temperature = 70
if (Temperature >69) and (Temperature < 100 )
THEN
openWindows;
Will work because if temperature is higher than 69 degrees and
temperature is lower than 100 degrees windows will open.
The code generated: numbered list 70-99

Temperature = 70
if (Temperature >69) or (Temperature < 100 )
THEN
openWindows;
Won't work because windows will stay closed due to temperature will
always be under 100 degrees the fault lies with the "or" "||" operator
which was used instead of the "and" (&&) operator.
The code generated: an infinite loop of never ending numbers that

Modern multi-tasking computer systems generally provide some way to
terminate a process from outside the process itself. For example, on
Windows you could have brought up the Task Manager (Ctrl-Alt-Del
nowadays), identified the process, selected it, and terminated it. Under
Linux, you could have used ps -eaf | grep <tasknameto find the task's
process ID (pid) and then used kill -9 <pidto terminate the task.

if he wants help (I assume that's why he posted to comp.lang.c)
then he's going to have to ask a clear question. His post seemed
to be part of a longer converstation or had been extracted from
another post. I found it unclear. Perhaps if he asked a clear
