⚠️ Special Conditions & Requirements

IMPORTANT: These conditions must be followed for code to work correctly:

1. Program Structure (REQUIRED)

Every Jatti program MUST start with sun_we and end with ja_we
sun_we must be at line 1 (no blank lines before it)
ja_we must be the last line
All code must be indented inside the sun_we...ja_we block

2. Functions (REQUIRED)

Functions MUST have a wapas_kar (return) statement - this is NOT optional
Functions must be defined inside the sun_we...ja_we block
Function calls MUST be in an assignment context: chal_oye result ban function_name()
Or in a print context: chilla_we function_name()

3. Control Flow Blocks

if...else blocks use indentation (Python-style), NO closing keyword
Multiple conditions: use nahin_taan_je for "else if", then nahin_taan for final "else"

Example:

je condition1
    fuddu_chiz do something
nahin_taan_je condition2
    fuddu_chiz do something else
nahin_taan
    fuddu_chiz default case

4. Loops

har_ek (for loop): Syntax is har_ek variable iterable
jadon_tak (while loop): Condition must follow the keyword
roko_oye_roko (break): Can only be used inside loops
chalo_oye_chalo (continue): Can only be used inside loops
Loop variables can be used in chilla_we but not in assignments (use temp variables instead)

5. Expressions & Function Calls

User-defined function calls must be in assignment context: chal_oye result ban function()
Nested function calls (e.g., range_banao(kinna_lamba(list))) are not supported - assign to a variable first
String concatenation with te only works in chilla_we statements, not in assignments
Use + for arithmetic, te for string output in print statements

➕ Operations

Arithmetic

sun_we
    chal_oye a ban 10
    chal_oye b ban 3
    
    chilla_we a + b          fuddu_chiz 13
    chilla_we a - b          fuddu_chiz 7
    chilla_we a * b          fuddu_chiz 30
    chilla_we a / b          fuddu_chiz 3.33
    chilla_we a % b          fuddu_chiz 1
ja_we

Comparison

sun_we
    chal_oye x ban 5
    
    chilla_we x vadha_hai 3     fuddu_chiz sach
    chilla_we x nikka_hai 10      fuddu_chiz sach
    chilla_we x barabar 5       fuddu_chiz sach
ja_we

Logical

sun_we
    chal_oye a ban sach
    chal_oye b ban jhoot
    
    je a te b                   fuddu_chiz AND operator
        chilla_we "Both sach"
ja_we

🔀 Control Flow

If-Else

sun_we
    chal_oye age ban 18
    
    je age vadha_hai 18
        chilla_we "Adult"
    nahin_taan
        chilla_we "Minor"
ja_we

For Loop

sun_we
    har_ek i range_banao(1, 5)
        chilla_we i
ja_we

Output:

While Loop

sun_we
    chal_oye count ban 0
    
    jadon_tak count nikka_hai 5
        chilla_we count
        chal_oye count ban count + 1
ja_we

roko_oye_roko & chalo_oye_chalo

sun_we
    har_ek i range_banao(1, 10)
        je i barabar 5
            roko_oye_roko
        nahin_taan
            chilla_we i
ja_we

🔧 Functions

Define Function

Important: Functions MUST be inside the sun_we...ja_we block and MUST have a wapas_kar (return) statement!

        chilla_we "Hello, " + name
        wapas_kar "Done"
    
    chal_oye result ban greet("Singh")
ja_we

Return Value

sun_we
    kaam add(x, y)
        wapas_kar x + y
    
    chal_oye result ban add(5, 3)
    chilla_we result
ja_we

Parameters
