Question

Create the following in swift:

Create a function that accepts a float for the wind speed and returns a string message based on its result. Use a Switch statement and ranges to handle all the cases, if something falls outside the list display the message “there is no such category”

Wind Speed (in MPH)

Result 74 to 95 - Category One

96 to 110 - Category Two

111 to 130 - Category Three

131 to 155 - Category Four

155 to the max possible float value - Category Five

Answer 1

Below is the solution:

swift code:

import Foundation

func windSpeed(windSpeed:Float)->String{ //create a windSpeed and pass the
    //declare the variable
    var speed:Int = 0
    var category:String = ""
    //check for the wind speed category
    if windSpeed >= 74 && windSpeed <= 95{
        speed = 1
    }
    else if windSpeed >= 96 && windSpeed <= 110{
        speed = 2
    }
    else if windSpeed >= 111 && windSpeed <= 130{
        speed = 3
    }
    else if windSpeed >= 131 && windSpeed <= 155{
        speed = 4
    }
    else if windSpeed > 155 {
        speed = 5
    }
  
    //pass the variable to set the wind category
    switch (speed){
    case 1:
        category = "Category ONe"
    case 2:
        category = "Category Two"
    case 3:
        category = "Category Three"
    case 4:
        category = "Category Four"
    case 5:
        category = "Category Five"
    default:
        category = "There is no such category"
    }
  
    return ("\(category)") //return the wind category
}

var wind:String = windSpeed(windSpeed: 96) //call a function with float value and that function will return the string value and store in wind string variable

print(wind) //print the wind value

sample output:

Category Two
