Explaining Scratch Code - Task 3

What are the 2 types of loop you have learned about?

• Conditional Loop

• Nested Loop

• Variable Loop

• Fixed Loop

Which loop goes round a set number of times?

• Conditional Loop

• Fixed Loop

Which loop keeps repeating until a condition is met?

• Conditional Loop

• Fixed Loop

What type of loop is the 'repeat until' construct in this piece of code?

• Fixed Loop

• Conditional Loop

What condition must be met for the loop to exit?

• The user must type the number 2

• The user must type the name 'David'

• The user must type the name 'Brocolli'

• The user must type the name 'answer'

Explain what the 'repeat until' section of code does here.

• It gets the user to input the name and the cost of a CD and takes the cost away from the pocket money. It continues to do this until pocket money is less than 1.

• It loops around and gets the user to enter the name and cosy of CDs they want to buy.

• It asks the user to enter their pocket money and takes away the cost of the CDs they enter. It continues to do this until pocket money is less than 1.

How is the 'pocket_money' variable stored in the computer's memory?

• It is stored as a decimal number

• It is stored as a binary number

• It is stored on the hard drive

Explain how this line of code works.

• It controls the time it takes for the program to execute.

• It controls the number of variables the program uses

• It controls the amount of pocket money the user has

• It controls at what point the conditional loop will exit.
