Here’s a simple Python example demonstrating some of these concepts:

# Variables and data types
name = "Alice"  # string
age = 30  # integer
height = 5.6  # float

# Control structure (if statement)
if age >= 18:
    print(f"{name} is an adult.")
else:
    print(f"{name} is a minor.")

# Function
def greet(person):
    return f"Hello, {person}!"

# Using the function
message = greet(name)
print(message)

# Data structure (list)
fruits = ["apple", "banana", "cherry"]

# Loop
for fruit in fruits:
    print(f"I like {fruit}.")

# Basic class
class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age
    
    def introduce(self):
        return f"My name is {self.name} and I'm {self.age} years old."

# Creating an object
alice = Person("Alice", 30)
print(alice.introduce())

This example covers variables, control structures, functions, data structures, loops, and a basic class. As you learn, try to understand how these concepts work together to create functional programs.
