Function Parameters - Swift Programming

Function parameters receive values from the call site and let one function work with different inputs.

Pass values into a function

function_parameters.swift

func addTax(price: Int, tax: Int) -> Int {
    return price + tax
}

let price = 
let tax = 3
let total = addTax(price: price, tax: tax)

print("price=\(price)")
print("total=\(total)")

func addTax(price: Int, tax: Int) -> Int {
    return price + tax
}

let price = 
let tax = 3
let total = addTax(price: price, tax: tax)

print("price=\(price)")
print("total=\(total)")

func addTax(price: Int, tax: Int) -> Int {
    return price + tax
}

let price = 
let tax = 3
let total = addTax(price: price, tax: tax)

print("price=\(price)")
print("total=\(total)")

parameters Parameters are local names inside the function body. Each call supplies the actual values used for that run.
