Flowchart Symbol Cheat Sheet

Symbol

Shape

Purpose

Input/Output

▰▰ Parallelogram

Data entry or display (e.g., INPUT age, PRINT
result)

Process

Rectangle

Calculations or data manipulation

Decision

◊ Diamond

Conditional branching (Yes/No paths)

Start/End

Oval

Beginning or termination point

Flow Line

➡️ Arrow

Direction of process flow


🖥️ Real World Examples of
Parallelogram Usage

  1. User
    Interaction

Diagram

The parallelogram captures both input (restock amount)
and output (report).

  1. File

❌ Common Misconceptions

  • Myth: “Parallelograms
    represent decisions.”
    Reality: Decisions use ◊ diamonds (e.g., “Is age >=
    18?”).
  • Myth: “All
    data operations use rectangles.”
    Reality: Rectangles are for processing (e.g., total
    = price * quantity), not I/O.

🔑 Why This Distinction
Matters

  1. Clarity
    in Design

    Parallelograms instantly signal data exchange points in complex workflows.
  2. Programming
    Translation

    Directly maps to code commands:

python

# Input Parallelogram → input()

name = input(“Enter your name: “) 

# Output Parallelogram → print()

print(f”Hello, {name}!”)

  1. Universal
    Standard

    Recognized in ISO 5807 and ANSI flowchart standards worldwide.

⚡ Pro Tips for Flowchart Design

  1. Label
    precisely
    : Use verbs like “Scan barcode” or “Display
    error” inside parallelograms.
  2. Combine
    with other symbols
    :

  1. Avoid
    ambiguity
    : Never use parallelograms for calculations (e.g., count
    = count + 1 belongs in a rectangle).
