Flowchart symbols are building blocks for the flowchart. Actions in the flowchart are represented and performed by different symbols.
Symbols are also called Shapes or Statements. Each flowchart symbol has a unique Shape. The flowchart symbols translate to programming statements in the source code. The terms “Symbol” , “Shape”, and “Statement” are used interchangeably.
To add a shape to the Flowgorithm flowchart, hover the mouse on the control line and right-click the mouse.
Flowchart symbols are classified into:
- Input/Output symbols
- Variables Declare/Assign symbols
- Control If/Call symbols
- Looping For/While/Do symbols.
- Breakpoint / Comment
Input Symbol reads user input from the keyboard and stores the data to a variable.
Output Symbol displays the data to the console window.
Declare symbol creates a variable in the flowchart.
Assign symbol stores the value to the specified variable.
If control structure makes a decision and controls the flow.
Call symbol invokes a function.
For loop structure is a definite repetition loop structure in the flowchart.
While loop structure is an indefinite repetition loop structure in the flowchart.
Do Loop is an indefinite repetition loop but executes the loop at least once.
Breakpoint symbol halts the flowchart execution. This symbol is used while debugging the flowchart.
Comment symbol adds documentation to the flowchart for the readers. Comments are ignored during the flowchart execution.
