Flowcrating:An Aid to Programming

               The goal of programming is to create an algorithm, a clear and unambiguous specification of the steps needed to solve a problem. Diagrams are important tools in specifying the logical steps required in problem. Solving and they are helpful in presenting the logical solution to a problem in visual form. A good example of these diagrams is the flowchart.

                Flowcharting is the process of creating the logical algorithm that leads to correct and efficient program design. Flowchart depicts the diagram of picture of the logic of a solution algorithm to the problem being addressed.

BASIC FLOW-CHARTING SYMBOL AND THEIR MEANINGS:

Terminal Box- It represents the beginning, or the end, or a point of interruption or delay in a program.

Input/Output Box- represents an I/O function on which makes data available for processing (input) or displaying of processed information (output).

Process Box- represents the process of executing a defined operation or group of operations that results in a change in value forms or location of interruption. It also functions as default symbol when no other symbol is available. It is sometimes referred to as assignment box.

Connector- Represents an entry form or exit to, to another part of the flowchart. Also serve as an off page connector. 

Initialization Box- It is used to initialize variables. Initialization is the process of assigning a value to a variable or set of variables.

Predefined Process- represents a named process consisting of one or more operations of program steps that are specified elsewhere’s

Annotation Symbol- represents the addition of descriptive information, comments, or explanatory notes or clarifications. The vertical line and the broken line may be placed on the left, or on the right.

Flow lines- represent the sequence of available information and executable operations. The lines connect other symbols and the arrow heads are mandatory and bottom-to-top flow.
