S3 Programming Revision

A 'Conditional Loop' could be used by a programmer.  What does this do?

• Repeats a section of code until something happens
• Repeats a section of code a set number of times

A 'Fixed Loop' could be used by a programmer.  What does this do?

• Repeats a section of code until something happens
• Repeats a section of code a set number of times

What are IF statements used for?

• Making decisions
• Repeating sections of code
• Storing values while the program is running
• Sharing finished programs online

What is a variable

• Anything that changes
• A space in memory used to store values while a program is running
• A construct for making decisions in a program
• A construct for repeating a section of code

Which of the following statements about procedures (making your own blocks in Scratch) is FALSE?

• Makes the code more readable

• Makes it easier to find errors in the code (debug)

• Means different programmers can work on different parts of a program at the same time making development faster

• Makes the program run faster

Top down design is:

• Identifying the main steps needed in your program

• Breaking down each step until it becomes easy to code

Stepwise refinement is:

• Identifying the main steps needed in your program

• Breaking down each step until it becomes easy to code

Which of the following is an advantage of good program design?

• Helps avoid coding errors

• Saves time because less errors need to be found and fixed

• Shows you understand the problem before you start

• All of the above
