Flowcharts Flashcards
What are flowcharts in programming?
Visual representations of algorithms or processes, with the purpose of making their logic and flow more understandable by using symbols and arrows
Steps in the program are illustrated.
What are the key aspects of a flowchart?
- Visual representation
- Use of Symbols
- Step-by-step flow
These aspects help in understanding the program’s logic and flow.
What are the purposes of flowcharts in programming?
- Visualization
- Communication
- Documentation
- Helps in the design process
Each purpose aids in understanding, maintaining, and modifying the program.
Mention all of the key structural aspects of flowcharts.
- Top-down flow
- Sequential flow
- Decision points or branching
- Loops or repetitions
- Connectors
- Modules
These aspects define how flowcharts are structured and interpreted.
Explain top-down flow in flowcharts.
Clear and intuitive reading direction
This structure helps users easily follow the logic.
What does sequential flow represent in flowcharts?
The process symbols connected by flow lines
This indicates the order of operations.
What are decision points in flowcharts?
Branching of the program based on conditions, labeled with the outcome
This allows the program to take different paths.
What are loops in flowcharts?
Repetitions that execute until a certain condition is met
Flow lines loop back to an earlier part of the chart.
What are connectors used for in flowcharts?
To maintain a clear and organized structure
On-page connectors are circles, off-page connectors are pentagons.
What are modules in flowcharts?
Blocks of code that perform a specific task, independent of the larger program
They can be scripted into the code as manageable units.
What symbols are used in flowcharts?
- Oval
- Rectangle
- Diamond
- Parallelogram
- Connectors
- Arrows
Each symbol has a specific purpose in the flowchart.
What are ovals used for in flowcharts?
Terminal which sets the start or end of a program
Start points are only one but endpoints may be multiple.
What are rectangles used for in flowcharts?
For process, action or operation to be performed
Examples include calculations or data manipulation.
What are diamonds used for in flowcharts?
They are decision points in which the program can branch based on a condition
This allows for conditional logic in the flow.
What are parallelograms used for in flowcharts?
For input or output operations
Examples include reading files, user input, or displaying information.
What are arrows used for in flowcharts?
To show the direction of the flowchart
They indicate how the process moves from one step to another.
How do flowcharts contribute to the initial stages of programming development?
- Analyzing the problem
- Breaking down into smaller steps
- Identifying potential issues
- Serving as documentation
This aids in understanding the program’s logic and structure before coding.
