Flowchart

“A flowchart is a step-by-step diagrammatic or pictorial representation of the algorithm for the solution of a problem” and flowcharting is the technique of drawing a flowchart.

Flowchart Helps in Program Development: It helps a person to understand the sequence of steps necessary to solve a given problem at a glance. Once developed and properly checked, the flowchart may be an excellent guide for writing the program.

Flowchart Symbols: Flowcharts are constructed by using special geometrical symbols. Each symbol represents an activity. The activity could be input/output of data, processing of data, taking a decision, terminating the solution, etc. The arrow joins the symbols to obtain a complete flowchart. Designs of flowcharts are very much flexible, so no two people can draw the exactly similar flowchart of a single problem.

The symbols described below are as per conventions followed by ISO (International Standards Organization).

1. Terminal Symbol: Rectangle with rounded sides (oval) is used to indicate BEGIN (or START) and END (or STOP) of a program.

2. Processing Symbol: Rectangle is used to indicate a set of processing operations such as for storage and arithmetic operations. Normally, the LET statement is used for such operations.

3. Input/Output Symbol: Parallelograms are used to represent input and output operations. Statements like INPUT, READ, and PRINT is used for these operations.

4. Decision Symbol: The diamond is used for indicating the step of the decision-making and therefore, known as the decision box. It is used to indicate the process of logic in a program, which may be used for getting an answer to a question or maybe for testing any condition. Computer-based on the answer selects the further flow path. The decision box must have at least two exits, although a third may be added sometimes if required.

5. Flow Lines: An arrow indicates the flow of operation. Every line in a flowchart must have an arrow on it.

6. Connector: If the flowchart extends over more than one page, the different parts can be joined with a connector. A circle is used for this purpose. A letter or digit is placed within the circle to indicate the link.

7. Predefined Process: A group of operations not detailed in the particular set of flowcharts.

8. Annotation or Comment Symbol: A broken line and bracket represent the annotation function – the addition of descriptive comments or notes for clarification of some statements.

Preparation for Using Flowcharts

General guidelines for flowcharting are given below:

  1. Ensure that the flowchart has logical start and finish points.
  2. Make the flowchart clear and easy to follow, so that it has a good visual impact.
  3. Make comparison instruction simple, i.e., capable of yes/no (true/false) answers.
  4. Try to construct a flowchart from the top to the bottom of a page and from the left to the right. If this convention is allowed, then a few arrows will be required.
  5. Avoid crossed flow lines whenever possible.

Advantages of Using Flowcharts

  1. Flowcharts give a clear graphical representation of the flow of program control.
  2. Flowcharts are a good visual aid for communicating the logic of a system to all concerned.
  3. They are language independent
  4. Current and proposed procedures may be understood more rapidly through the use of flowcharts. A programmer can chart a lengthy procedure more easily with the help of a flowchart than by describing it by means of written notes.
  5. They are useful in the alterations of programs. The programmer can easily find the spot in the flowcharts where changes are to be made.
  6. Flowcharts are precise and do not include steps involved to embellish a program.

Limitations of Using Flowcharts

  1. Alterations and Modifications: If alterations (or changes) are required in the program logic, the flowchart may require redrawing completely.
  2. Complex Logic: When the logic of the program is complex, the flowcharts quickly become complex and clumsy.
  3. Standardization: Program flowcharts are neither such a natural way of expressing procedures nor are they easily translated into a programming language. (BCA 1st Year Flowcharts Notes Study Material)
  4. Reproduction: As the flowchart symbols cannot be typed, reproduction of flowcharts is often a problem.
  5. The link between Conditions and Actions: Sometimes it becomes difficult to establish the linkage between various conditions and the related actions.
