swift
Parameters: x: Int
An integer number to be squared
Returns: Returns the square of the input integer
The find-square function in Swift takes an integer value as an input and returns its square. Useful in many mathematical calculations and algorithms.
Hello there, dear programmer! Welcome to this post where we'll go through an exciting adventure of Swift programming. No worries if you're a novice, this guide is designed to help you master the process of writing a function in Swift that calculates the square of a number. Happy coding!
First, we need to define our function in Swift. We'll call it findSquare and it will take one argument, an integer which we'll call num.
func findSquare(num: Int) {
}
Now, we need to get the square of the input number. In Swift, we square a number by multiplying it with itself. We'll do this inside the function and store it in a variable called square.
func findSquare(num: Int) {
let square = num * num
}
Finally, we need to return this square from our function. This is done using the return keyword in Swift.
func findSquare(num: Int) -> Int {
let square = num * num
return square
}
Now we have our findSquare function, which takes an integer as input and returns its square. Here is the complete implemented function code.
func findSquare(num: Int) -> Int {
let square = num * num
return square
}
This function can be used in any Swift program where we need to calculate the square of a number.
This function utilizes the basic mathematical principle of squaring a number, which means multiplying the number by itself. In mathematical notation, if `x` is the number, squaring it is represented as `x^2`. Squaring numbers is a fundamental operation in arithmetic and algebra.
