  3. 3. FLOWCHART Topic Name
  4. 4. A Flow chart •Is a type of diagram that represents an algorithm, workflow or process, showing the steps as boxes of various kinds, and their order by connecting them with arrows. • Flow charts are used in analysing ,designing, documenting or managing a process or program in various fields.
  5. 5. I. Flow chart are used in designing and documenting complex processes or programs. II. Like other types of diagrams , they help visualize what is going on and thereby help the people to understand a process , and perhaps also find flaws, bottlenecks , and other less- obvious features within it. III. There are many different types of flowcharts , and each type has its own repertoire of boxes and notational conventions.
  6. 6. Overview The two most common types of boxes in a flow chart are: 1) a processing step, usually called activity, and denoted as a rectangular box 2) a decision , usually denoted as a diamond.
  7. 7. Terminator Represented as circles , ovals or rounded rectangles, usually containing the word “Start” or “End” , or another phrase signalling the start or end of a process , such as “submit inquiry” or “receive product”. Start / end
  8. 8. Arrows • Showing “flow of control”. • An arrow coming from one symbol and ending at another symbol represents that control passes to the symbol the arrow points to . • The line for the arrow can be solid or dashed. • The meaning of the arrow with dashed line may differ from one flowchart to another and can be defined in the legend
  9. 9. Processing • Represented as rectangles. • Use it to represent an event which is controlled within the process. • Typically this will be a step or action which is taken. • In most flowcharts this will be the most frequently used symbol. • Examples: “ Add 1 to X”; “replace identified part”; “save changes” or similar. processing
  10. 10. INPUT/ OUTPUT Represented as a parallelogram. Represents material or information entering or leaving the system, such as customer order (input) or a product (output). Example: Get X from the user; display X. Input/output
  11. 11. DECISION A decision or branching point. Lines representing different decisions emerge from different points of the diamond. decision
  12. 12. 1)Program flowchart 2)System flowchart
  13. 13. Program flowchart: shows the sequence of instructions in a program or subroutine. These instructions are followed to procedure the needed output START INPUT PROCESS OUTPUT DECISION END
  14. 14. Draw a flowchart to find the largest of three numbers A, B & C.
  15. 15. number. Start Read n i=1 f=1 If i<=n Print “factorial ” , F Stop f = f * i i = i + 1
