💻 Difference between Structured and Object-Oriented Programming

🔹 1. Definition

Feature	Structured Programming (SP)	Object-Oriented Programming (OOP)
Definition	Programming paradigm focused on functions/procedures and step-by-step logic.	Programming paradigm focused on objects, classes, and their interactions.
Approach	Top-down approach (Break program into functions).	Bottom-up approach (Build objects first and integrate).

---

🔹 2. Core Concepts

Feature	SP	OOP
Unit of Design	Functions / Procedures	Objects / Classes
Data Handling	Data is separate from functions	Data is encapsulated inside objects
Key Concept	Sequence, Selection, Iteration	Encapsulation, Inheritance, Polymorphism, Abstraction

---

🔹 3. Examples of Languages

SP	OOP
C, Pascal	Java, C++, Python, C#

---

🔹 4. Advantages & Disadvantages

Feature	SP	OOP
Advantages	Simple, easy to understand, less overhead	Reusable code, maintainable, scalable, models real-world problems
Disadvantages	Poor reusability, hard to maintain large programs	More complex to learn, requires planning and design

🔹 5. Summary

• Structured Programming → Focuses on functions, step-by-step flow, procedural style.

• Object-Oriented Programming → Focuses on objects, encapsulation, reusability, real-world modeling.

💡 Structured vs Object-Oriented Programming – Visual Comparison Chart

1️⃣ Layout

• Two Columns: Left → Structured Programming, Right → Object-Oriented Programming

• Header: “Structured Programming vs Object-Oriented Programming” (center top, bold)

2️⃣ Left Column – Structured Programming (SP)

• Box Color: Light Blue (#cce6ff)

• Contents (bullets):

  • Program = Sequence of instructions

  • Functions / Procedures

  • Data separate from functions

  • Top-Down Approach

  • Low Reusability

  • Examples: C, Pascal

3️⃣ Right Column – Object-Oriented Programming (OOP)

• Box Color: Light Orange (#ffe6cc)

• Contents (bullets):

  • Program = Collection of Objects

  • Encapsulation (Data + Methods)

  • Bottom-Up Approach

  • High Reusability & Maintainability

  • Real-world Modeling

  • Examples: Java, C++, Python, C#

4️⃣ Optional Enhancements

• Arrows connecting SP → OOP to show evolution from procedural to object-oriented style

• Icons for “Function” (SP) and “Object/Class” (OOP) for visual effect

• Use bold or slightly bigger font for main concepts like “Encapsulation”, “Top-Down”

📌 Pro Tip for Blog:

• Keep each column symmetrical, neat spacing

• Use contrasting colors for readability

• Add small icons to make the diagram attractive and easy to remember
