1. Nested Conditional
Nested if-else statements allow checking multiple conditions in a structured way.
Nested if-else statements multiple conditions check करने के लिए structured तरीका देती हैं।
- Always ensure proper indentation for readability.
- Good for multiple decision making.
- Combine with logical operators for complex conditions.
- Readability के लिए proper indentation जरूरी है।
- Multiple decision making के लिए useful।
- Complex conditions के लिए logical operators combine करें।

Example: Check student grade based on marks
Example: Marks के आधार पर grade check करना
2. Ternary Operator
Ternary operator allows writing if-else statements in a concise single line.
Ternary operator single line में if-else statements लिखने देता है।
- Syntax: condition ? expressionIfTrue : expressionIfFalse
- Useful for simple condition checks.
- Can be nested for multiple conditions.
- Syntax: condition ? expressionIfTrue : expressionIfFalse
- Simple condition checks के लिए useful।
- Multiple conditions के लिए nested किया जा सकता है।

Example: Determine eligibility based on age
Example: Age के आधार पर eligibility check करना
3. Switch Statement
Switch statements are used to perform different actions based on different conditions, cleaner than multiple if-else for discrete values.
Switch statements अलग-अलग discrete values के आधार पर actions perform करने के लिए use होते हैं, multiple if-else से cleaner।
- Use switch for discrete values (like days of week).
- Each case should end with a break to prevent fall-through.
- Default handles unexpected values.
- Discrete values (जैसे week days) के लिए switch use करें।
- हर case के बाद break डालें ताकि fall-through न हो।
- Default unexpected values handle करता है।

4. Logical Operators
Logical operators allow combining multiple conditions to make more complex decisions.
Logical operators multiple conditions को combine करके complex decisions बनाने में मदद करते हैं।
- AND (&&), OR (||), NOT (!) operators are commonly used.
- Useful for validating multiple constraints.
- Combine with if-else or ternary for concise logic.
- AND (&&), OR (||), NOT (!) commonly use होते हैं।
- Multiple constraints validate करने के लिए useful।
- If-else या ternary के साथ combine करें concise logic के लिए।
