Crafting a Swift Function to Calculate the Perimeter of an Octagon

Hello there, programmer! Welcome to this blog post. Today we're going to play it cool and walk you through the steps on how to program a swift function to calculate the perimeter of an octagon. No need for fancy jargon or language-specific nuances; we'll keep it simple and straightforward. Let's code!

Step 1: Understanding the Problem

We need to calculate the perimeter of an octagon. The formula for the perimeter of an octagon is P = 8a where a is itself the length of one side of the octagon. In our swift function, we should accept a single argument - the length of one side of the octagon.

func perimeterOctagon(sideLength: Double) {}

Step 2: Implementing the Formula

Within our function, we implement the formula for the perimeter of an octagon by multiplying the given side length by 8.

func perimeterOctagon(sideLength: Double) {
    let perimeter = 8 * sideLength
}

Step 3: Returning the Result

Finally, we return the calculated perimeter from the function.

func perimeterOctagon(sideLength: Double) -> Double {
    let perimeter = 8 * sideLength
    return perimeter
}

Conclusion

By following these steps, we've created a function in Swift that calculates the perimeter of an octagon given the length of one side. The full code is as follows:

func perimeterOctagon(sideLength: Double) -> Double {
    let perimeter = 8 * sideLength
    return perimeter
}
