What do we call the pictorial representation of steps for solving a particular problem?
- A.
Flowchart
- B.
Algorithm
- C.
Flow lines
- D.
Option 4
Correct Answer
A. FlowchartExplanation
A flowchart is a visual representation of the steps or processes involved in solving a specific problem. It uses various symbols and shapes to depict the flow of information, decisions, and actions. Flowcharts are commonly used in computer programming, engineering, and problem-solving to provide a clear and organized representation of the problem-solving steps. They help in understanding and communicating complex processes and enable easy identification of errors or inefficiencies in the solution.Rate this question:
