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.
A simple flowchart representing a process for dealing with a non-functioning lamp.
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.
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.
Example 2 Draw a flowchart to find the largest of three numbers A, B, and C.
Example 3 Draw a flowchart for computing factorial N (N!) Where N! = 1?2?3?....N.
