swift
Parameters: number1: Double, number2: Double
number1 and number2 are the two numbers to be multiplied
Returns: Returns the multiplication result of two numbers
This swift function receives two integers as parameters and returns the multiplication of these numbers.
Welcome, fellow programmer! This blog post will guide you through a simple yet fundamental task in Swift programming - creating a function to multiply two numbers. Stay tuned and walk through the steps below to create concise and efficient function. It's easy, straightforward, and a great skill to have in your toolkit. Let's get down to business!
In Swift, you want to define your function with a clear and descriptive name. For this case, we can name our function multiplyTwoNumbers
. The function should have two parameters, both of which will be of type Int
.
func multiplyTwoNumbers(_ num1: Int, _ num2: Int) {
}
This function is simple, as we only need to multiply the two input integers. So within our function definition, we use Swift's *
operator to multiply the arguments.
Let's implement our plan within the function.
func multiplyTwoNumbers(_ num1: Int, _ num2: Int) {
let result = num1 * num2
}
In the function, we now need to add the return
keyword to ensure our function outputs the result.
func multiplyTwoNumbers(_ num1: Int, _ num2: Int) -> Int {
let result = num1 * num2
return result
}
Finally, let's test our function by calling it and printing the result:
let multiplicationResult = multiplyTwoNumbers(4, 5)
print(multiplicationResult) // Output should be 20
Conclusion:
We have successfully created a function that multiplies two integers. The function multiplyTwoNumbers
takes two integers as parameters and returns their product.
Here's the final code:
func multiplyTwoNumbers(_ num1: Int, _ num2: Int) -> Int {
let result = num1 * num2
return result
}
let multiplicationResult = multiplyTwoNumbers(4, 5)
print(multiplicationResult)
A mathematical operation signified by the sign 'x', used to combine numbers.
