Iterating Over Arrays

Iterating Over Arrays in Kotlin

Arrays are a fundamental data structure that store multiple values of the same type. In Kotlin, you often need to perform operations on each element of an array, such as printing values, modifying data, or searching for specific items. This process is called iteration.

What Is Iteration?

Iteration means repeating a set of actions for every item in a collection, like an array. When you iterate over an array, you access each element one by one in order.

Why Iterate Over Arrays?

• Access each value in an array;
• Perform actions like calculations or printing for every element;
• Search for specific values or patterns in the array;
• Modify elements based on certain conditions.

Common Ways to Iterate

Kotlin provides several ways to loop through arrays, including:

• Using a for loop to access each item directly;
• Using array indices to access elements by their position;
• Using built-in functions such as forEach for concise iteration.

Understanding how to iterate over arrays efficiently is essential for working with data in Kotlin programs.
