Unlock the Power of Loops in Kotlin

Loops are a fundamental concept in programming, allowing developers to perform repetitive tasks with ease and efficiency. In Kotlin, loops can be used to achieve a wide range of tasks, from simple to complex.

Looping Through the Alphabet

One common use case for loops is to iterate through a sequence of characters, such as the English alphabet.

In Kotlin, you can loop through the uppercase alphabets (A to Z) using a for loop. But how does it work? Internally, the loop iterates through the ASCII character codes, which range from 65 (A) to 90 (Z). This means you can easily modify the loop to display lowercase alphabets (a to z) by simply replacing ‘A’ with ‘a’ and ‘Z’ with ‘z’. The internal loop then iterates through the ASCII character codes 97 (a) to 122 (z).

Example 1: Uppercase Alphabets

for (char in 'A'..'Z') {
    print(char)
}

Example 2: Lowercase Alphabets

for (char in 'a'..'z') {
    print(char)
}

By leveraging the power of loops in Kotlin, you can create efficient and effective code that gets the job done. Whether you’re working on a simple task or a complex project, loops are an essential tool to have in your toolkit.
