*✅ Programming Concepts Interview Questions with Answers*

1️⃣ *What is the difference between compiled and interpreted languages?*
✅ Compiled Language: Code is converted into machine code before ex*****on. Faster performance. Examples: C, C++, Java (partially compiled)
✅ Interpreted Language: Code executes line by line at runtime. Slower but easier debugging. Examples: Python, JavaScript

2️⃣ *What is OOP? Explain its 4 pillars*
✅ Object-Oriented Programming (OOP): A programming paradigm based on objects, classes, and real-world modeling.
🔹 4 Pillars:
1. Encapsulation: Wrapping data + methods together.
2. Abstraction: Showing only essential features.
3. Inheritance: One class acquires properties of another.
4. Polymorphism: Same function behaves differently.

3️⃣ *Difference between Abstraction vs Encapsulation*
Abstraction hides implementation details, while Encapsulation protects data.
Abstraction focuses on what to show, Encapsulation focuses on how to restrict access.

4️⃣ *What is Polymorphism? Give a real example*
✅ Polymorphism = One interface, multiple behaviors. Same method performs different actions based on context.
🎯 Real Example: A person behaves differently: At home → son, At office → employee

5️⃣ *What is the difference between Stack and Heap memory?*
Stack Memory stores function calls & local variables, automatically managed, and faster access.
Heap Memory stores objects & dynamic memory, manually or garbage collected, and slower access.

6️⃣ *What is Recursion? When should you avoid it?*
✅ Recursion: A function calling itself until a base condition is met.
🚫 Avoid recursion when memory is limited, deep recursive calls are possible, or iterative solution is simpler.

7️⃣ *What is the difference between Pass by Value and Pass by Reference?*
✅ Pass by Value: Copy of variable passed, changes don't affect original.
✅ Pass by Reference: Original variable reference passed, changes affect original.

8️⃣ *What are mutable vs immutable objects?*
✅ Mutable Objects: Can be changed after creation. Examples: List, Dictionary
✅ Immutable Objects: Cannot be modified after creation. Examples: String, Tuple

9️⃣ *What is a Deadlock?*
✅ Deadlock: A situation where two or more processes wait for each other indefinitely.

10️⃣ *What is Multithreading?*
✅ Multithreading: Running multiple threads (tasks) simultaneously within a program. Benefits: Better performance, faster ex*****on.
