Creating a flowchart
A flowchart is a common type of diagram, which represents an algorithm or process, showing the steps as
boxes of various kinds, and their order by connecting these with arrows. Flowcharts are used in analyzing,
designing, documenting or managing a process or program in various fields .
A typical flowchart from older Computer Science textbooks may have the following kinds of symbols:
Start and end symbols
Arrows
Processing steps
Input /Output
Conditional or decision
A number of other symbols that have less universal currency, such as:
A
Document
repr
esented as a rectangle with a wavy base;
A Manual input represented by parallelogram, with the top irregularly sloping up from left to right.
An example would be to signify data-entry from a form;
A parallelogram indicate operation or judgment conditions.
Data are represented by a histogram.
Flowcharts may contain other symbols, for example, connector is represented by a circle, which is usually
pointed by some arrows. Among the arrows, only one point outward. Some flowcharts only use one arrow
pointing to another, which represent repeated actions. It is called loop in computer science. For example,
a loop graph includes a connector, processing steps, a condition for exiting the loop and arrows.
