Flowcharts

A flowchart is a graphical representation of an algorithm. It consists of a set of symbols. Each symbol represents a specific kind of activity depicted in the algorithm. A typical problem would involve accepting input, processing the input and displaying the output. The processing would involve the computations and the decisions that are being taken.

Advantages of Flowcharts

• Flowcharts are a better method of communicating logic than pseudocode and decision tables.

• Flowcharts help in analyzing the problem effectively.

• Flowcharts acts as a guide during the program development phase.

• It is easier to debug errors in logic using a flowchart.

• Flowcharts help in maintaining the programs because programmers can easily understand the logic.

Disadvantages of Flowcharts

• A lengthy flowchart may extend over multiple pages, which reduces readability.

• Drawing a flowchart using any graphical tool is a time consuming process.

• The changes made to a single step may cause redrawing the entire flowchart.

• A flowchart representing a complex algorithm may have too many flow lines. This reduces readability. In addition, it is very time - consuming to draw such flowcharts.
