FLOW CHART

Flow Chart in Computer Programming (Complete Guide)

What is a Flow Chart?

A flowchart is a graphical or pictorial representation of an algorithm or process. It uses different symbols to represent steps such as input, output, processing, and decision-making.

Flowcharts are widely used in computer programming, system design, and problem-solving because they make complex logic easy to understand.

Why are Flowcharts Important?

Flowcharts provide several benefits:

• They help programmers focus on the logic of the problem without worrying about programming syntax.
• They make it easier to detect logical errors before writing code.
• They improve communication between developers and non-technical people.
• They act as a blueprint for writing efficient programs.
• They simplify debugging and maintenance.

Basic Flowchart Symbols and Their Meaning

Here are the most commonly used symbols:

• Oval (Terminator) → Represents Start/End
• Parallelogram → Input/Output operation
• Rectangle → Processing step (calculation)
• Diamond → Decision making (Yes/No)
• Arrow → Flow of control

Example 1: Flowchart to Find Sum of Two Numbers

Steps:

1. Start
2. Input two numbers (A and B)
3. Calculate Sum = A + B
4. Display Sum
5. End

Explanation:

This flowchart takes two inputs, performs addition, and shows the result.

Example 2: Flowchart to Check Even or Odd Number

Steps:

1. Start
2. Input number (N)
3. Check if N % 2 == 0
4. If Yes → Print "Even"
5. If No → Print "Odd"
6. End

Explanation:

The decision symbol is used here to check whether the number is divisible by 2.

Tips to Create Good Flowcharts

• Always start from "Start" and end with "End".
• Keep the flow from top to bottom or left to right.
• Use proper symbols for each step.
• Avoid crossing lines to keep it clean.
• Make it simple and easy to understand.

Conclusion

Flowcharts are a powerful tool for planning and understanding programs. They help reduce errors, improve clarity, and make coding easier. Every beginner in programming should learn how to create and use flowcharts effectively.
