Rules For Drawing Flowcharts

While drawing a flowchart the following rules should be followed:
1. Use conventional flowchart symbols. Each symbol should have one exit point except the decision symbol. As far as possible each symbol should also have one entry point and in the case of decision symbol, it is a must.
2. The flow of control in the problem can be shown with the help of arrows. But, the flow lines should not cross each other.
3. The processing logic within the flowchart should flow from top to bottom and from left to right.
4. The instructions written within the various flowchart symbols should be independent of programming languages.

5. The flow lines coming out of the decision symbol should be properly labelled.
6. If the flowchart becomes large and complex (on same page) then make use of ordinary connector symbols to avoid crossing of flow lines.
7. Every flow chart must have the start and End points.
