Reflect on what you've learned so far. Understanding these basic concepts will serve as the foundation for your future programming. In the next lesson, you will explore control structures that allow your code to make decisions.

Homework: Your First Program

Your First Steps in Swift/Kotlin

Your First Steps Quiz

Control structures are the backbone of programming logic. They allow your code to make decisions based on certain conditions, enabling your app to respond dynamically to user inputs. Understanding these concepts is crucial for creating a functional quiz app.

Control structures can be categorized into three main types: sequential, selection, and repetition. Each type plays a distinct role in how your code executes.

**Sequential:** Code executes line by line in the order it appears.

**Selection:** Code executes based on conditions (e.g., if statements).

**Repetition:** Code executes repeatedly until a condition is met (e.g., loops).

If statements allow your code to execute certain blocks based on specific conditions. For example, if a user selects a correct answer, you can display a success message.

if userAnswer == correctAnswer {
    print("Correct! Great job!")
} else {
    print("Oops! Try again.")
}

Loops are essential for executing certain actions multiple times. In your quiz app, you might want to loop through a list of questions, allowing users to answer each one.

for question in questions {
    print(question)
    // Code to check answer
}

By combining if statements and loops, you can create interactive quiz logic. For instance, you can loop through each question and check if the answer is correct, providing immediate feedback to the user.

for question in questions {
    print(question)
    let userAnswer = getUserInput() // Function to get user input
    if userAnswer == correctAnswer {
        print("Correct!")
    } else {
        print("Wrong answer, try again.")
    }
}

When working with control structures, beginners often make mistakes such as forgetting to close brackets or misplacing conditions. Here are some tips to avoid these pitfalls:

Always check your syntax and indentation.

Test your code frequently to catch errors early.
