Definition of Algorithm
To write a logical step-by-step method to solve the problem is called algorithm, in other words, an algorithm is a procedure for solving problems. In order to solve a mathematical or computer problem, this is the first step of the procedure. An algorithm includes calculations, reasoning and data processing. Algorithms can be presented by natural languages, pseudo code and flowcharts, etc.
Definition of Flowchart
A flowchart is the graphical or pictorial representation of an algorithm with the help of different symbols, shapes and arrows in order to demonstrate a process or a program. With algorithms, we can easily understand a program. The main purpose of a flowchart is to analyze different processes. Several standard graphics are applied in a flowchart:
|
Symbol |
Purpose |
Description |
|
|
Flow line |
Indicates the flow of logic by connecting symbols. |
|
|
Terminal(Stop/Start) |
Represents the start and the end of a flowchart. |
|
|
Input/Output |
Used for input and output operation. |
|
|
Processing |
Used for arithmetic operations and data-manipulations. |
|
|
Decision |
Used for decision making between two or more alternatives. |
|
|
On-page Connector |
Used to join different flowline |
|
|
Off-page Connector |
Used to connect the flowchart portion on a different page. |
|
|
Predefined Process/Function |
Represents a group of statements performing one processing task. |
