Arrows represent the direction of flow of control and relationship among different symbols of flowchart.Įxample : Draw a flow chart of a program to print largest of two numbers. Eight steps that insure complete preparation and execution of a flowchart are- Research the problem Decide on the method of solution Plan the solution Outline the system by drawing the system flowchart Check the system flowchart Draw a detailed program flowchart for each program Check the program flowchart Test the program flowchart and. Flow Lines : Flow lines indicate the exact sequence in which instructions are executed. Note: See the section What the flowchart shapes represent for information on which shapes to use for each step. For each step in the process that you are documenting, drag a flowchart shape onto your drawing. Connectors : Whenever flowchart becomes complex or it spreads over more than one page, it is useful to use connectors to avoid any confusions.

Input/Output : A parallelogram denotes any function of input/output type. Terminal is the first and last symbols in the flowchart.Ģ. A pause/halt is generally used in a program logic under some error conditions. ![]() Terminal : The oval symbol indicates Start, Stop and Halt in a program’s logic flow. It makes use of symbols which are connected among them to indicate the flow of information and processing.ġ. Flowchart are very helpful in writing program and explaining program to others. Flowchart is a diagrammatic representation of an algorithm.
