Introduction to Nested Loops

Nested loops, as the name suggests, are loops within loops. They allow you to create more complex and structured patterns of repetition. To understand this concept better, let's break it down:

  • Outer loop: the outer loop is the main loop that controls the flow of your program. It's responsible for repeating the entire process multiple times;

  • Inner loop(s): inside the outer loop, you can have one or more inner loops. These inner loops have their own iteration control and can run multiple times before the outer loop progresses to the next iteration.

Imagine you have several baskets, each containing apples, and your goal is to mark every one in each basket. You start by taking one basket at a time and looking inside. For each fruit in the basket, you take it out, mark it, and then put it back. Once you're done with the items in one basket, you move on to the next and repeat the process until everything in all baskets is marked.

// Outer Loop: Process of Taking a New Basket with Apples
for (int basket = 0; basket < totalBaskets; ++basket) {
    // Inner Loop: Process for Individual Apples in the Basket
    for (int apple = 0; apple < applesInBasket; ++apple)
    {
        // Take an apple from the basket
        auto currentApple = getApple(apple);
        markApple(currentApple); // Mark the apple
        putApple(currentApple); // Put the marked apple back into the basket
    }
    // End the process of taking a new basket
}
