MY UNDERSTANDING ON PROGRAMMING SESSION DAY 2 :

Deep Dive into Operators, Language Types, and Programming History** ✅ 1. In Java: & vs && — What’s the Difference? Operator Name What it Does When to Use & Bitwise AND Compares each bit of two numbers Used in bitwise logic && Logical AND Checks if both conditions are true Used in if statements // Bitwise int a = 5; // 0101 int b = 3; // 0011 System.out.println(a & b); // 0001 → 1 // Logical if (a > 0 && b ` ✅ 3. Compare Operators in Java, Python, JS, C++ Concept Java Python JavaScript C++ Equality ==, .equals() ==, is, equals() ==, === == Strict Equality N/A N/A === N/A Increment/Decrement ++, -- ❌ Not available ++, -- ++, -- Power Math.pow ** ** (ES6) pow() ✅ 4. What is Floor Division? Floor Division (//) gives the largest integer less than or equal to the division result. 7 // 2 = 3 (not 3.5) ✅ 5. Why Is It Called "Floor" Division? Because it "rounds down" the result to the nearest lower whole number — it applies the mathematical floor function. ✅ 6. Power in Python: / vs // vs ** Operator Meaning Output Type Example / Normal Division Float 5 / 2 = 2.5 // Floor Division Integer 5 // 2 = 2 ** Power (Exponent) Integer/Float 2 ** 3 = 8 Other languages: Java: Math.pow(2, 3) JS: 2 ** 3 C++: pow(2, 3) ✅ 7. Why Python is Dynamically Typed? No need to declare type. x = 10 # x is int x = "hi" # now x is string

// Bitwise
int a = 5;  // 0101
int b = 3;  // 0011
System.out.println(a & b); // 0001 → 1

// Logical
if (a > 0 && b < 10) {
   System.out.println("Valid range");
}

7 // 2 = 3  (not 3.5)

x = 10  # x is int
x = "hi"  # now x is string
