In order to write computer programming without any logical error, it is recommended programmers prepare a rough writing showing the steps involved in the program. This is called an algorithm. An algorithm presents step-by-step instruction required to solve any problem. These steps can be shown diagrammatical using a flowchart.
Flowchart is a symbolic or diagrammatic representation of an algorithm. It uses several geometrical figures to represent the operations and arrows to show the direction of flow.
Programmers often use it as a program-planning tool to solve a problem. It makes use of symbols which are connected among them to indicate the flow of information and processing.
Flowchart are very helpful in writing program and explaining program to others.
Start / Stop (Terminal): Represents the beginning and the end of the flowchart.
Input/Output: Represents the values to be given by the user and the results to be displayed.
Processing: Represents the arithmetic operation to compute a value.
Checking / Decision making: Represents the logical checking to decide the flow sequence.
Preparation: As the names states, any process step that is a Preparation process flow step, such as a set-up operation.
Connector: Represents the Continuity of the flowchart in another place / page.
Arrows: Represents direction of flow.
