Flowchart is a graphical or symbolic representation of an algorithm. It is the diagrammatic representation of the step-by-step solution to a given problem.

Advantages of Flowchart

The benefits of flowcharts are as follows:

  1. Communication: Flowcharts are better way of communicating the logic of a system to all concerned.
  2. Effective analysis: With the help of flowchart, problem can be analysed in more effective way.
  3. Proper documentation: Program flowcharts serve as a good program documentation, which is needed for various purposes.
  4. Efficient Coding: The flowcharts act as a guide or blueprint during the systems analysis and program development phase.
  5. ProperDebugging:The flowchart helps in debugging process.
  6. Efficient Program Maintenance: The maintenance of operating program becomes easy with the help of flowchart. It helps the programmer to put efforts more efficiently on that part.

Disadvantages of Flowchart

Although a flowchart is a very useful tool, there are a few limitations in using flowcharts which are listed below:

  1. Complex logic: Sometimes, the program logic is quite complicated. In that case, flowchart becomes complex and clumsy.
  2. Alterations and Modifications: If alterations are required the flowchart may require re-drawing completely.
  3. Reproduction: As the flowchart symbols cannot be typed, reproduction of flowchart becomes a problem.
  4. The essentials of what is done can easily be lost in the technical details of how it is done.
