Flex Programming Language

Welcome to the Flex Online Compiler! This is your gateway to learning and using the Flex programming language.

Getting Started

Flex is a modern programming language designed for simplicity and performance. The online compiler provides a complete development environment with real-time execution and interactive capabilities.

Your First Program

print("Hello, World!")

Variables and Data Types

// Variable declaration
rakm x = 10          // Integer variable  
y = 20               // Type inference
name = "Flex"        // String variable
is_valid = true      // Boolean variable

String Interpolation

Flex supports modern string interpolation using {variable} syntax:

x = 10
y = 20
print("The sum of {x} and {y} is {x + y}")

Control Structures

Conditional Statements

age = 18
if (age >= 18) {
    print("You are an adult")
} else {
    print("You are a minor")
}

Loops

// For loop
for (i = 0; i < 5; i++) {
    print("Iteration: {i}")
}

// While loop
rakm count = 0
while (count < 3) {
    print("Count: {count}")
    count = count + 1
}

Functions

function greet(name) {
    return "Hello, {name}!"
}

result = greet("World")
print(result)

Interactive Input

Flex provides two functions for user input:

• da5l() - Reads user input (preferred method)
• input() - Alternative input method

print("What is your name?")
name = da5l()
print("Hello, {name}!")

Features

• Type Inference: Automatic type detection
• String Interpolation: Modern {variable} syntax in strings
• Interactive I/O: Real-time input via da5l() and input() functions
• Modern Syntax: C-style control structures
• Real-time Execution: Compiled and executed in web environment
