Some important points to follow in flowchart are given below. Read them carefully.
8 The direction of logic flow should be top to bottom and left to right.
8 Arrow head lines are used to show the flow of logic, information or sequence of
the program.
8 A flowchart must have only one start and stop box symbol.
8 The steps should be in a sequence and should be arranged in a proper manner.
Though, flowcharts are useful in efficient coding, debugging and analysis of a
program, drawing flowchart in very complicated in case of complex programs and
often ignored.
