Introduction
•
Code Visual to Flowchart is a
code maintain and understand
software that is capable to rapidly
analyze source code and to
display in the flowchart window
the graphical presentation of
currently edited code.
Code Visual to Flowchart is
composed of a code editor and a
flowchart Window .The flowchart
engine is so fast that the flowchart
can be constantly displayed as the
alternative view of the currently
edited source code.
You can export flowchart of
current edited code as Bitmap on
any flowchart expand level you
like ,Help you to create code
flowchart document easily.

Code Visual to Flowchart supports all primary program languages,such as
C ,C++ ,Java ,JavaScript ,VB ,BASIC ,
Qbasic ,ASP ,Vbscript ,Delphi ,Pascal ,PHP ,C#,VB.NET ,Perl... Code
Visual to Flowchart is composed of a code editor and a flowChart
window .
In the various implementations of flow charts, they are usually displayed in a
way that all the source code is partitioned in fragments and displayed inside
the drawn blocks.
Code Visual to Flowchart is based on different philosophy . The Flow
Chart engine is so fast that the Flow Chart can be constantly displayed as
the alternative view of the currently edited source code.
Code Visual to Flowchart does not display code in flow charts. Since flow
charts can always be synchronized with Editor, it is enough to display the
code structure from the source inside of the flow chart. The real code can
always be edited in its natural way - inside of the Editor window.
•
Another strategy with which Code Visual to Flowchart
fights against enormously large flow charts is the
concept of expand levels. The maximum depth of
displaying the enclosed blocks can always be specified
and easily changed.
Code Visual to Flowchart features the quickest
navigation of source code and it is also a good assistant
when you are working on a program IDE .
Goals is to understand these following :What is flowchart ??
Why we will use flow chart & when!! ??
Get Know to the environment of Code Visual to

What is a Flowchart?
• A flowchart is a
diagram that
depicts(“yosor”) the
“flow” of a program.
• The figure shown
here is a flowchart
for the paycalculating program
in Chapter 1.

Four Flowchart Structures
•
•
•
•
Sequence
Decision
Repetition
Case
Sequence Structure
• a series of actions are performed in sequence
• The pay-calculating example was a sequence
flowchart.
Decision Structure
• One of two possible actions is taken, depending
on a condition.
Decision Structure
• A new symbol, the diamond, indicates a yes/no question.
If the answer to the question is yes, the flow follows one
path. If the answer is no, the flow follows another path
NO
YES
Decision Structure
• In the flowchart segment below, the question “is x < y?”
is asked. If the answer is no, then process A is
performed. If the answer is yes, then process B is
performed.
NO
YES
x < y?
Process
A
Process
B
Decision Structure
• The flowchart segment below shows how a decision
structure is expressed in C++ as an if/else statement.
Flowchart
NO
C++ Code
YES
if (x < y)
x < y?
a = x * 2;
else
Calculate a
as x plus y.
Calculate a
as x times 2.
a = x + y;
Decision Structure
• The flowchart segment below shows a decision structure
with only one action to perform. It is expressed as an if
statement in C++ code.
Flowchart
NO
C++ Code
YES
x < y?
if (x < y)
a = x * 2;
Calculate a
as x times 2.
Repetition Structure
• A repetition structure represents part of the program that
repeats. This type of structure is commonly known as a
loop.
Repetition Structure
• Notice the use of the diamond symbol. A loop tests a
condition, and if the condition exists, it performs an
action. Then it tests the condition again. If the condition
still exists, the action is repeated. This continues until the
condition no longer exists.
Repetition Structure
• In the flowchart segment, the question “is x < y?” is
asked. If the answer is yes, then Process A is performed.
The question “is x < y?” is asked again. Process A is
repeated as long as x is less than y. When x is no longer
less than y, the repetition stops and the structure is
exited.
YES
x < y?
Process A
Repetition Structure
• The flowchart segment below shows a repetition
structure expressed in C++ as a while loop.
Flowchart
C++ Code
while (x < y)
x++;
YES
x < y?
Add 1 to x
Controlling a Repetition
Structure
• The action performed by a repetition structure must
eventually cause the loop to terminate. Otherwise, an
infinite loop is created.
• In this flowchart segment, x is never changed. Once the
loop starts, it will never end.
• QUESTION: How can this
flowchart be modified so
YES
it is no longer an infinite
x < y?
Display x
loop?
Controlling a Repetition
Structure
• ANSWER: By adding an action within the repetition that
changes the value of x.
YES
x < y?
Display x
Add 1 to x
A Pre-Test Repetition Structure
• This type of structure is known as a pre-test repetition
structure. The condition is tested BEFORE any actions
are performed.
YES
x < y?
Display x
Add 1 to x
A Pre-Test Repetition Structure
• In a pre-test repetition structure, if the condition does not
exist, the loop will never begin.
YES
x < y?
Display x
Add 1 to x
A Post-Test Repetition Structure
• This flowchart segment shows a post-test
repetition structure.
• The condition is tested AFTER the actions
Display x
are performed.
• A post-test repetition structure always
performs its actions at least once.
Add 1 to
x
YES
x < y?
A Post-Test Repetition Structure
• The flowchart segment below shows a post-test
repetition structure expressed in C++ as a do-while loop.
C++ Code
Display x
Flowchart
do
{
cout << x << endl;
x++;
} while (x < y);
Add 1 to
x
YES
x < y?
Case Structure
• One of several possible actions is taken,
depending on the contents of a variable.
Case Structure
• The structure below indicates actions to
perform depending on the value in
years_employed.
CASE
years_employed
1
bonus =
100
2
bonus =
200
3
bonus =
400
Other
bonus =
800
Case Structure
If years_employed =
2, bonus is set to 200
If years_employed =
1, bonus is set to 100
1
bonus =
100
If years_employed =
3, bonus is set to 400
If years_employed is
any other value,
bonus is set to 800
CASE
years_employed
2
bonus =
200
3
bonus =
400
Other
bonus =
800
Combining Structures
• Structures are commonly combined to create more
complex algorithms.
• The flowchart segment below combines a decision
structure with a sequence structure.
YES
x < y?
Display x
Add 1 to x
Combining Structures
• This flowchart segment
shows two decision
structures combined.
NO
YES
x > min?
Display “x is
outside the limits.”
NO
YES
x < max?
Display “x is
outside the limits.”
Display “x is
within limits.”

4. Code Visual to Flowchart works with flowchart window to help programmers to edit
complex source code easily. We can click on any part of the edited code ,and then
the related part of flowchart will be highlighted. Flowcharts can be exported in MS
Visio or BMP formats on any flowchart expand level. So developers can create code
flowchart documents easily.
5. Current edited code can directly be printed or be exported as RTF or HTML with
colors and the format is just the same as its appearance in editor. That is real what
you see is what you get.
6. Code Visual to Flowchart has 2 kinds of flowcharts: The first one is displayed in a
way that all the source code is partitioned in fragments and displayed inside the
drawn blocks. The other one does not display code in flow chart. Since flow chart can
always be synchronized with Editor, it is enough to display the code structure from
the source inside of the flow chart. The real code can always be edited in its natural
way - inside of the Editor window.

7. Additional features of Code Visual to Flowchart include:
Synchronization between flowchart and source code in editor; unlimited
programming flow chart expand levels; Syntax highlighting for Source
code; Support all Windows system, include Vista and so on.
The Top 5 Reasons To Use Flowcharts
(why we use flow chart )
Sometimes it's more effective to visualize something graphically that it is to describe it
with words. That is the essence of what flowcharts do for you. Flowcharts explain a
process clearly through symbols and text. Moreover, flowcharts give you the gist of the
process flow in a single glance. The following are some of the more salient reasons to
use flowcharts.
•
•
•
Process Documentation / Training Materials
Another common use for flowcharts is to create process documentation.
Although this reason overlaps with regulatory and quality management
requirements (below), many non-regulated businesses use flowcharts for
their documentation as well. These can range in form from high-level
procedures to low-level, detailed work instructions.
You may think that this applies mainly to large organizations, but small
companies can greatly benefit from flowcharting their processes as well.
Small enterprises need to be nimble and organized. Standardizing their
processes is a great way to achieve this.
•
•
Workflow Management and Continuous Improvement
Workflows don't manage themselves. To ensure that you are meeting your
customers' needs, you need to take control of your business processes. The
first step to workflow management is to define the current state of your
processes by creating an "As-Is Flowchart". That allows you to analyze your
processes for waste and inefficiency. After you have identified areas for
process improvement, you can then craft new flowcharts to document the
leaner processes.
•
•
Programming
Information technology played a big influence on the use and spread of
flowcharts in the 20th century. While Dr. W. Edwards Deming was
advocating their use in quality management, professionals in the data
processing world were using them to flesh out their programming logic.
Flowcharts were a mainstay of procedural programming, however, and with
the advent of object oriented programming and various modeling tools, the
use of flowcharts for programming is no longer as commonplace as it once
was.
Notation :The “Code Visual to Flowchart” is Upper case tools (support analysis and
design phases)
So its process analysis tools
