1.0 Introduction: Visual Programming
i. What is programming
It is a field of skill that entails the creation of computer applications, websites, and software.
Programming is the creation of digital language. It provides a way for human to interact with the
computer through a set of instructions called code.
ii. Types of Programming
Text-based: programming language using script or text and think like computer
Visual-based: programming language using illustration that make sense to human
iii. Visual programming language
In computing, a visual programming language (VPL) is any programming language that lets users create
programs by manipulating program elements graphically rather than by specifying them textually. A
VPL allows programming with visual expressions, spatial arrangements of text and graphic symbols,
used either as elements of syntax or secondary notation. For example, many VPLs (known as dataflow
or diagrammatic programming) are based on the idea of "boxes and arrows", where boxes or other
screen objects are treated as entities, connected by arrows, lines or arcs which represent relations.
iv. Example of visual programming
It can be divided into a noted categories such as Educational, Multimedia, Video Games,
System/simulation, Automation, Data warehousing/ business intelligence. Refer to

2.0 The Algorithm, Flowchart and Programming
Algorithm
It is a logical step-by-step approach to solve the problem. This is the first step in the process to solve a
mathematical or computer problem. An algorithm includes calculations, reasoning, and data processing.
Algorithms can be presented by natural languages, pseudocode, and flowcharts, etc.
According to Dr. Christoph Koutschan, a computer scientist working at the Research Institute for Symbolic
Computation (RISC) in Austria, he has surveyed voting for the important types of algorithms. As a result,
he has listed 32 crucial algorithms in computer science. Despite the complexity of algorithms, we can
generally divide algorithms into six fundamental types based on their function.
Pseudocode is an artificial and informal language that helps programmers develop algorithms.
Pseudocode is a "text-based" detail (algorithmic) design tool. The rules of Pseudocode are reasonably
straightforward. All statements showing "dependency" are to be indented.
Flowchart
A flowchart is the graphical or pictorial representation of an algorithm with the help of different symbols,
shapes, and arrows to demonstrate a process or a program. With algorithms, we can easily understand a
program. The main purpose of using a flowchart is to analyse different methods.
Terminal Box - Start / End
Input / Output
Process / Instruction
Decision
Connector / Arrow

Basic Flow Control
Behind all of the software we use on a daily basis, there's a code being run with all sorts of terms
and symbols. Surprisingly, it can often be broken down into three simple programming structures
called Sequential, Selections, and Loops. These come together to form the most basic instructions
and algorithms for all types of software. There are three basic constructs in an algorithm.
1. Sequential - The simplest control statement. A sequence of sequential statements runs from the
top to bottom (from the first to the last block of flowchart). Runs exactly once. Example:
1) unlock the door
2) open the door
3) enter the room
4) switch on the light
5) close the door behind you
2. Selections (also known as decisions) – Is used to make choices based on information. Instead of
following a specific order of events, they ask a question in order to figure out which path to take
next. An algorithm can be made more intelligent or jump to different parts of the program.
if
if-else
switch (with cases)
The previous example about entering the room could be changed to consider for different
conditions. For instance, it could change to:

9
1) IF the door is locked, then unlock the door, ELSE do nothing (go to next instruction)
2) IF the door is closed, then open the door, ELSE do nothing
3) Enter the room
4) IF the room is dark, then switch on the light, ELSE do nothing
5) Close the door behind you
The sequence of actions is carried out is selected based upon the information provided. The only
way for a computer to discover the circumstances is to collect inputs and compare it to known
values.
In this case, known values would be values such as 'locked' or 'unlocked', 'closed' or 'open'. The
computer looks at the door and checks to see if its current state matches 'closed' and 'locked'. If
it matches 'locked', the door needs to be unlocked. Otherwise, nothing should be done.
*CASE
The selection IF-THEN-ELSE is useful if the choices are binary, such as 'locked' or 'unlocked' ('yes'
or 'no').
The alternative to the IF-THEN-ELSE structure is the CASE structure. Using CASE, the algorithm
searches a list of options until it finds the correct condition. For example, on a multiple-choice
quiz, the answers might be A, B or C - the correct condition is either A, B or C.

10
Basically, IF-THEN-ELSE looks for the correct option from two choices where CASE looks at the
correct option from multiple choices.
3. Loops (iteration) - The process of repeating sections of a program to achieve a particular target or
goal.
for
for-each (also known as range-based)
while
do-while
Computer programs can use different types of loops; infinite loops (repeat forever), count-
controlled loops (repeat a number of times) and condition-controlled loops (repeat until
something happens).
a. Infinite loops
A sequence on an infinite loop keeps repeating until the user terminates the program or it crashes.
For example, on a desktop computer, the operating system has a program that continually checks
your USB ports to see if you have plugged in a device. Even after you have plugged in a device, it
still continues to check for any new devices.
b. Count-controlled loop
Count-controlled loops are used to make a computer do the same thing a specific number of
times. The count-controlled loop can be described as a FOR loop. The program repeats the action
FOR a number of times. The count-controlled loop can be described as the FOR-NEXT structure.
The program repeats the action between the FOR and NEXT number of times.
c. Condition-controlled loops
A program could be made more intelligent by programming it to avoid hazards. For example, if
the robot vehicle is 3 cm from the edge of the table and you tell it to move forwards 5 cm, it will
drive off the edge of the table. To stop this from happening, you might write a condition-
controlled loop like this:
move forward
repeat until (touching table edge)
Condition-controlled loops can be used to add a high degree of intelligence to a computer
system.

11
WHILE
Condition-controlled loops are also called WHILE loops or WHILE-ENDWHILE statements. A WHILE
loop code is repeated based on a certain condition. The condition could be 'true' or 'false'. The
WHILE loop executes while a condition is true. Whether the condition is met or not is checked at
the beginning of the loop. If the condition is 'true' it repeats, if not then the code is not executed.
DO WHILE
A similar condition-controlled loop is a DO WHILE loop. This method differs from a WHILE
condition-controlled loop in that the condition is checked at the end of the loop. If the condition
is ‘true’, the loop repeats. Thus, the code in the loop is executed at least once.

12
Infinite loops
Condition-controlled loops can result in intentional or unintentional infinite loops. If we wanted
to loop indefinitely, we could set a condition that would never be met, thus iterating infinitely.
The following examples would result in an infinite loop:
WHILE:
count = 1
while count <>0:
print(count)
count +=1
DO WHILE:
count = 1
do
print(count)
count+=1
while count <>0
REPEAT UNTIL:
count = 1
repeat
print(count)
count+=1
until count =0
It is important to check that the conditions we set can be met if we wish them to be.
Differentiating between the four types of loops
A count-controlled loop (FOR loop) iterates the number of times specified in the loop.
With a WHILE condition-controlled loop the iteration occurs indefinitely as long as the specified
condition is being met. If the condition is already met, the code in the loop is never executed.
With a DO WHILE condition-controlled loop the iteration occurs indefinitely as long as (or until)
the specified condition is met. The code in the loop is executed at least once.

13
With a REPEAT UNTIL condition-controlled loop the iteration occurs indefinitely until the
specified condition is met. The code in the loop is executed at least once.
An infinite loop can occur with all condition-controlled loops but not with a count-controlled
loop.

Flowchart: A flowchart is simply a graphical representation of steps. It shows steps in sequential order
and is widely used in presenting the flow of algorithms, workflow or processes. Typically,
a flowchart shows the steps as boxes of various kinds, and their order by connecting them with arrows.
