Learn to Code: Swift Playgrounds

What is Swift Playground?

• A tool used to write a pseudo code for any program

• Advanced tool to create applications

• Powerful programming language created by Apple

• An algorithmic designer tools

What best describes an algorithm?

• A step-by-step series of operations

• Only calculations that use advanced mathematics

• The computer equivalent of rhythm

• The same thing as an identifier

What is a sequence ?

• specific actions for the computer to perform

• Is the order in which the commands are given

• is the repeated actions

• is the algorithmic thinking skills

What is coding?

• The repeated actions in the program

• Algorithmic thinking skills

• Telling a ​computer what to do.

• None of the above

What is a mistake in code called?

• error

• debug

• bug

• misfunction

By writing commands you give instructions to do something. Which command sequence is formatted correctly?

• collectGem()

  moveForward()

• collect Gem ()

  move Forward ()

• (moveForward)

  (collectGem)

• moveForward() collectGem()

Longer sequences of code can involve ----------------

• less bugs.

• more bugs.

• fewer variables.

• fewer actions.

If the code is not running as intended, what could be the cause of the problem?

• bugs

• interface

• sequence

• code

Sometimes we solve coding problems by combining existing commands to create a new behavior. This process is called composition. Which is an example from Swift Playgrounds of composition?

• When I told the bot to collectGem()

• When I learned to toggleSwitch()

• When I created a turnRight() with three turnLeft()

• When I write 1 line of code.

With the following code, what would you expect to see happen when you run your code?

func saySomething ( ) {

print ("Functions are awesome")

saySomething ( )

}

saySomething ( )

• Functions are awesome, once

• Functions are awesome, twice

• Functions are awesome, repeated over and over and over...

• Nothing
