This document discusses several activities and examples involving the "For Next" loop in Visual Basic. It explains how the first "For" loop determines the numbers included and the second "For" loop determines the arrangement. Examples include counting down from 1 to 5, calculating the sum of positive integers, and using variables to print parts of a word. Combo boxes and option buttons are also discussed as ways to provide input choices for programs. Binary codes are summarized as representing characters through combinations of zeros and ones.

1. HAPPY NEZZA B. ARANJUEZ 10 – EINSTEIN
This activity is part of the “For Next” topic in our Visual Basic class and when Ma’am Reyes gave
this activity to us we were all confused of how we will do the activity. But in this activity I was able to
realize ad understand how the first “For” is important. It determines the numbers included in that line
while the second “For” determines the arrangement and the number of integers for that line.
Another “For Next” activity from the worksheet where we did a “countdown-like” number
progression from 1 to 5. The “For x” served as the indicator of which numbers will be included in the
pattern and the “For y” for how the numbers will progressed if it is from least to greatest of vice-versa or
if it goes in reverse arrangement or the normal increasing order. The “Step -1” makes the order go in a
reverse form and if you don’t put it in the code, the standard form is the increasing order.

2. This is the second activity in the worksheet where in you will get the sum of
the positive integers less than the digit you input as long as it is not equal or
greater than zero. It is still part of the topic “For Next”.
The first activity
in the worksheet is
when you will
count how many
numbers a re
printed if you
input the code
given. So as
shown for the
result here it is.
I enjoyed making this program since it will become helpful if I am to compute for the
factorial of a digit. Its code is somehow same with the code for summation all you have to do
is to change the addition sign into a multiplication sign.

3. Third activity from the
worksheet, three different other
examples for the “For Next”
progression: (1) the first has a
Step -1 to indicate reverse order
of the digits. (2) Doesn’t have
the Step -1, it means it is the
standard or normal order, the
counting form from least to
greatest. (3) this one is the most
complex among the three since I
had to research about it in the
net and the dollar sign ($) is
important because it will serve
as a variable for the word
“COMPUTER” . The “For y” is for
the part before the complete
word COMPUTER and the “For
x” is for the part after that word.

4. These are all the
example activites from the recent
powerpoint Ma’am Reyes gave
us. It is about the usage of List
Box (If you want to use a
dropdown type of option list).
Combo Box (If it includes
different process for each
option), Check Box (if your are
to use an individual checklist)and
Option Button (for the
dial/circular type of having a
checklist with a varying process
for each option).

5. In this activity we used the combo box to set the
choices of the operations to be used in the program. As you
choose an operation, it will serve as the chosen operation for
your program. It will be shown as a drop down list and once
you choose and click your chosen symbol it will perform its
process.

6. First of all, I did not really understand this topic. But as I further searched about
Binary Codes, I learned that the numbers were like switches and each character has its
binary denotation. Only the character with “ones” are given a value and the ones with
“zeros” have also their own denotation. And as you put them together you can encode
a new code for the series of characters. It’s about decoding and substitution of values
among zeros and ones.
