Welcome, learners! Let's dive deeper into Kotlin programming by combining loops and decision-making structures. We'll explore the power of integrating loops, like for and while, with conditional structures such as if and when. Such combinations can make our programs significantly more dynamic and flexible.
We'll revisit the conditional constructs in Kotlin. You'll recall the if construct, which executes a block of code when a condition is met. For example:
Compound conditions, built with logical operators like && (AND) and || (OR), can also be used:
Next, let's review the when construct. Like a compact form of if-else chains, when matches its argument with different conditions:
We can merge conditional statements with loops. Here's an if construct within a for loop:
A for loop can also easily incorporate a when construct:
We can apply the same combined approach with while loops. Here's a while loop with an if construct:
A while loop can also include a when construct:
Now, let's consider real-life examples. Imagine you're organizing a kids' game. Each child has cards numbered from 1 to 10. If the card number is even, it's placed in Box A; otherwise, it's placed in Box B.
Consider a scenario of a smart home garden watering system. Flowers are watered on Monday, Wednesday, and Friday, whereas trees are watered on Tuesday and Thursday:
By slightly extending our basic understanding of loops and conditions, we can create intricate and useful code!
We've reviewed the if and when constructs and have learned how to use these within for and while loops. Coming next are practice exercises where you'll apply these concepts. Remember— the best way to learn is by doing. Good luck!
