What is a Flowchart

A flowchart is a visual diagram used to represent the steps of a process, system, or algorithm. In computer science, flowcharts are commonly used to illustrate how an algorithm or program works. Flowcharts use standardized symbols to represent different types of actions, decisions, or operations, making them easy to understand and analyze. These diagrams help developers, analysts, and users map out the logical flow of a process or software program.

Flowcharts are often used in the early stages of software development to plan algorithms, define workflows, or troubleshoot issues. They make it easier to visualize how data or decisions flow through a system, which aids in understanding complex processes and identifying potential issues.

Common Flowchart Symbols

• Oval (Start/End): Indicates the beginning or end of a process.
• Rectangle (Process): Represents a step or task in the process.
• Diamond (Decision): Indicates a decision point where different paths can be taken based on conditions.
• Arrow (Flow Line): Shows the direction of the process flow.
• Parallelogram (Input/Output): Represents input or output actions in the process.

Uses of Flowcharts in Computing

• Designing algorithms and programs
• Documenting workflows and business processes
• Troubleshooting and debugging code
• Visualizing system architecture and data flow
• Explaining complex processes to stakeholders or team members

Advantages of Using Flowcharts

• Easy to understand and communicate complex processes
• Helps identify bottlenecks and inefficiencies in a process
• Useful for planning, organizing, and structuring software development
• Supports better decision-making and problem-solving
