Nick Walter Challenges (Part 2)

So 5 days without coding is a poor effort! I have a very small amount of time (20 minutes) to do some then I will make up for it by doing more at the weekend. As it's a short time, I'm going straight back to Nick Walter's challenges, rather than Angela's more in-depth and theoretical stuff. Right here we go!

Start time - 15:55

Print and comments

// 1) Write a single line comment

// 2) Write a multi line comment

// 3) Print a String, Int and Double all in one print statement

These should all be fine. Let's do it!

// Here is my single line comment

/* Multi line comment:

 This will go over several lines

 No problem at all

 */

var name = "Josh"

var myAge = 33

var shoeSize = 8.5

print("My name is \(name), my age is \(myAge) and my shoe size is \(shoeSize)")

All easy peasy!

Boolean and If Statements

//1) Make a boolean variable that's true

//2) Make a boolean constant that's false

//3) Make a constant called age that's an Int. Then make an if statment that prints "adult" if age is 18 or older. And f younger than 18, print "minor".

//4) Make an if statement that also uses an OR

Again, these look like no problem. Last ones for now though!

//1

var canSwim = true

//2

let fatherTedFan = false

//3

let newAge = 23

if newAge >= 18 {

    print("Adult")

} else {

    print("Minor")

}

//4

var gotName = "Tywin Lannister"

if gotName.hasSuffix("Lannister") {

    print("A Lannister alway pays his debts")

} else if gotName.hasSuffix("Stark") {

    print("Winter is coming")

} else {

    print("Neither a Lannister nor a Stark!")

}

Ok so I misunderstood the last one...I was looking at OR as if else. Let's just do the last one again...

if gotName.hasSuffix("Lannister") || gotName.hasPrefix("Tywin") {

    print("This is an important name")

} else {

    print("Not imporant enough!")

}

Boom!

Finish time - 16:08 (13 minutes total)

Well, 13 minutes is better than nothing. Basically 'keeping my eye in' before I do a proper session at the weekend. All of the challenges were very easy to be honest but they're worth doing as they're application rather than passive learning. Until tomorrow!
