AQA GCSE Computer Science - 3.2.11 Structured programming

1. What is meant by structured programming?

• Programming in modules where each function or procedure has a specific purpose
• Programming with advanced programming techniques
• Programming with small programs
• <br />Programming with if statements and iteration

2. How can you achieve structured programming in the design stage?

• By decomposing the problem into smaller sub-problems
• By adding one big algorithm
• By designing the user interface

• By declaring variables and validation

3. What is the main benefit of structured programming?

• The whole program can be understood better
• You can program without functions and procedures

• You can use advanced programming techniques
• You can use selection and iteration

4. What is another benefit of structured programming?

• Subroutines will only be called when they're needed and they can be called multiple times

• Better use of advanced programming techniques

• Better use of global variables

• Better use of selection and iteration

5. Explain how abstraction helps with structured programming?

• The focus is only on the relevant details that will be useful for modules/users

• Listing the variables to avoid global variables

• Subroutines will only be called when they're needed

• Decomposes the problem into smaller sub-problems

6. What will structured programming avoid the use of?

• Global variables
• Local variables
• Global and local variables

• Constants

7) What does a parameter mean?

• It is used in a subroutine to refer to one of the pieces of data provided as input to the subroutine.
• A condition which is passed through a loop which makes a loop stop iterating
• A structure, series, or process, the end of which is connected to the beginning
• A definite or clear expression used to print an output

8) What is a disadvantage of Structured programming?

• The structure of a program needs to be planned very well
• It is hard to implement in a practical scenario
• It can only be carried out by a large programming team
• It uses a lot of electricity

9) Which is an example of a Structured programming language?

• All of them
• Java
• Python
• C++

11) How are blocks used in structured programming?

• They are used to enable groups of statements to be treated as if they were one statement
• They are used to create for loops while iterating through extensive lists
• They are used to make the programming easier to read for other members of a team
• They are used to sort the information into sections so that it is easier to debug
