A flowchart is a pictorial representation of an algorithm, workflow or process, showing the steps as boxes of various kinds, and their order by connecting them with arrows. It is used to show the sequence of steps and logic of solution to a given problem. Flowcharts are used in analyzing, designing, documenting or managing a process or program in various fields.
The terminal symbol is used to indicate the beginning (START) and ending (STOP) in the program logic flow.
Process symbol is used to illustrate a process, action or an operation. These are
represented by rectangles.
The input/output symbol is used to denote any type of input data or output information.
The decision symbol is used in a flowchart to indicate a point at which a decision has to be
made and a branch to one of two or more alternative points are possible.
Flowlines with arrowheads are used to indicate the flow of operation. It shows the
exact sequence in which the instructionsare to be executed.
Flowcharts are better way of communicating the logic of a system.
With the help of flowchart, problem can be analyzed in more effective way
therefore reducing cost and wastage of time.
The flowcharts act as a guide or blueprint during the systems analysis and program
development phase.
The flowchart helps in debugging a process.
The maintenance of operating program becomes easy with the help of flowchart. It
helps the programmer to put efforts more efficiently on that part.
