Explain flowchart in detail? (FEB 2009/FEB 2010)
The benefits of flowcharts are as follows:
a. Communication: Flowcharts are better way of communicating the logic of a system to all concerned.
b. Effective analysis: With the help of flowchart, problem can be analyzed in more effective way.
c. Proper documentation: Program flowcharts serve as a good program documentation, which is needed for various purposes.
d. Efficient Coding: The flowcharts act as a guide or blueprint during the systems analysis and program development phase.
e. Proper Debugging: The flowchart helps in debugging process.
f. 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.
Advantages
Logic Flowcharts are easy to understand. They provide a graphical representation of actions to be taken.
Logic Flowcharts are well suited for representing logic where there is intermingling among many actions.
Disadvantages
Logic Flowcharts may encourage the use of GoTo statements leading to software design that is unstructured with logic that is difficult to decipher.
Without an automated tool, it is time-consuming to maintain Logic Flowcharts. Logic Flowcharts may be used during detailed logic design to specify a module.
However, the presence of decision boxes may encourage the use of GoTo statements, resulting in software that is not structured. For this reason, Logic Flowcharts may be better used during Structural Design.
A flowchart is a schematic representation of an algorithm or a stepwise process, showing the steps as boxes of various kinds, and their order by connecting these with arrows. Flowcharts are used in designing or documenting a process or program.
A flow chart, or flow diagram, is a graphical representation of a process or system that details the sequencing of steps required to create output. A flowchart is a picture of the separate steps of a process in sequential order.
