Which flowchart symbol represents a subroutine or a module?
Question: Which flowchart symbol represents a subroutine or a module?
The flowchart symbol that represents a subroutine or a module is the predefined process symbol. It is a rectangle with rounded corners and the name of the subroutine or module written inside.
The predefined process symbol is used to represent any process that is already defined and can be used without further explanation. This can include subroutines, modules, functions, or even entire programs.
Here is an example of a flowchart using the predefined process symbol:
Start
-> Get input from user
-> Call subroutine: CalculateTotal()
-> Display total to user
-> End
The subroutine CalculateTotal() is a predefined process that is responsible for calculating the total of a set of numbers. The flowchart does not need to explain how this subroutine works, because it is already defined.
Predefined process symbols can be used to make flowcharts more concise and easier to read. They can also help to avoid repetition, as the same subroutine or module can be used multiple times in a flowchart.
Here are some examples of predefined processes that can be represented with the predefined process symbol:
- Subroutines
- Modules
- Functions
- Entire programs
- Library functions
- Operating system calls
- External APIs
The predefined process symbol is a versatile tool that can be used to represent a wide variety of processes in flowcharts.
