2  The flowchart is a visual presentation of the flow of data through an information processing systems, the operations performed within the system and the sequence in which they are performed.  Flowcharts are generally drawn in the early stages of formulating computer solutions. Flowcharts facilitate communication between programmers and business people.

3 A simple flowchart representing a process for dealing with a non-functioning lamp.

4  Flowcharts are usually drawn using some standard symbols; however, some special symbols can also be developed when required. Flowchart symbolNameDescription ProcessAn operation or action step. Alternate ProcessAn alternate to the normal process step. TerminatorA start or stop point in a process. DecisionA question or branch in the process. Data(I/O) Indicates data input and output to and from a process. DocumentA document or report. Multi-DocumentMultiple documents. Flow LineIndicated the flow direction.

5  Now we will present some flowchart examples on flowcharting for proper understanding of this technique:  Example 1 Draw a flowchart to find the sum of first 50 natural numbers.

6  Example 2 Draw a flowchart to find the largest of three numbers A, B, and C.

7  Example 3 Draw a flowchart for computing factorial N (N!) Where N! = 1?2?3?....N.

8  Communication.  Effective analysis.  Proper documentation.  Efficient Coding.  Proper Debugging.  Efficient Program Maintenance.

9  Complex logic.  Alterations and Modifications.  Reproduction.  The essentials of what is done can easily be lost in the technical details of how it is done.
