Example: Iterative Factorial

This example highlights LaadleLang's jabtak (while) loops, variable mutation, and conditional breaking (bas and chal) inside an iterative sequence.

The Code

// A function that calculates a factorial iteratively without recursion
kaam calculate_factorial(n) toh
    agar n < 0 toh
        bol "Factorials are only for non-negative numbers!"
        wapas
    
    laadle result hai 1
    laadle current hai n
    
    jabtak current > 1 toh
        result hai result * current
        current hai current - 1
        
    wapas result

// Output the sequence 
laadle num hai 5
bol "Factorial of " + num + " is:"
bol calculate_factorial(num)

What's Happening?

1. Variables & Reassignment: We declare variables using laadle. Inside the jabtak loop, we simply omit the laadle keyword to mutate the existing result and current variables rather than declaring new ones.
2. Loop Condition: The jabtak current > 1 toh loop continually runs its nested block until the condition becomes falsy.
3. Execution Guarding: The agar n < 0 toh code block acts as a safety barrier. If triggered, it prints a warning and invokes a bare wapas to break out directly without iterating or causing an infinite loop.
