Q
Why would a developer who knows high and low-level programming choose to use high-level programming?
A
- High-level languages have built-in functions and libraries
- High-level languages have more support/help
- High-level languages have structures (such as selection and iteration)
- High-level languages can be less machine-dependent/more portable and they are more compatible
- requires fewer lines of code to be written
- It is (usually) quicker to develop code in high-level languages
- It is easier to find mistakes in code
- The code is easier to maintain//understand
- It is easier to structure code in high-level languages

Q
What tests can a developer use to improve testing of their code?
A
- could be tested with only 1s
- It could be tested with different lengths of input
- It could be tested with an input where the 1s and 0s vary
- It could be tested with an input where the last two numbers are different
- It could be tested with the empty string
- It could be tested with a string of length one
- It could be tested with two runs of 0s separated by a run of 1s / two runs of 1s separated by a run of 0s
- It could be tested with invalid data (such as 1010abc

Q
What only applies to local variables?
A
- is only accessible//declarable//within scope (in the subroutine)
- only exists while the subroutine/program block is executing

Q
How do developers use structured programming?
A
- subroutines with parameters = more readible
- parameter within subroutines = reused
- iteration = more efficient
- indentation

Q
Explain how the developer could use a combination of an array and records to store information about music records:
A
- put each song in a record with the song title + datatype of each field
- assign it to a variable named song 1 song 2 etc.
- as they have the same record structure = collect them in an array
- array name should be something like song_progranm_array
