Question 1

things that keep a program maintained?

Answer 1

comments

indentation

suitable variable names

sub programs

Question 2

what is defensive design?

Answer 2

anticipates how users might misuse their program then attempt to prevent that

ensure code is well maintained

reduce errors through testing

Question 3

two types of errors?

Answer 3

logic error

syntax error

Question 4

what is a syntax error?

Answer 4

when the compiler/interpreter doesnt understand part of the code because it doesnt follow the programming language

causes the whole code to not run

Question 5

what is a logic error?

Answer 5

when the compiler or interpreter is able to run the program but it does something unexpected

Question 6

what are the two types of testing?

Answer 6

iterative testing

final testing

Question 7

what is iterative testing?

Answer 7

testing the program while it is being developed

repeating a section of code

Question 8

what is final testing?

Answer 8

testing the whole program when it is finished to check it works as intended

Question 9

what is normal data?

Answer 9

what the user is likely to input

Question 10

what is boundary data?

Answer 10

values at the limit of what the program can handle

Question 11

what is invalid data?

Answer 11

inputs with the correct dats type that should be rejected by the program

Question 12

what is erroneous data?

Answer 12

incorrect data type that should be rejected by the program

Question 13

what is a trace table?

Answer 13

give a simple way of testing if code works correctly

keeps track of values and variables as you go through the code

Question 14

what is a translator?

Answer 14

translates the code from high level to low level for the computer to read

Question 15

example of high level language?

Answer 15

python

CC+

Question 16

example of low level language?

Answer 16

machine code

assembly language

Question 17

what type of code do computers only understand?

Answer 17

machine code
1s and 0s

Question 18

two types of translators?

Answer 18

compilers

interpreters

Question 19

what is a compiler?

Answer 19

translates a high level language directly into machine code

creates one executable file

Question 20

what is an interpreter?

Answer 20

take each instruction and call sub routines to carry out that instruction

SIMPLE:

translates and runs the source code one instruction at a time and doesn’t create an executable file

Question 21

what does IDE stand for?

Answer 21

integrated development environment

Question 22

what is an IDE?

Answer 22

a piece of software that provides features to help a programmer develop their program

Question 23

examples of IDE’s?

Answer 23

error diagnostics

syntax highlighting

automatic indents

Question 24

what is error diagnostics?

Answer 24

helps the programmer find where they made a mistake

Question 25

what is syntax highlighting?

Answer 25

displays different variables of the code in colours

Question 26

what is computational thinking?

Answer 26

steps taken to find the best solution to a complex problem

Question 27

what are the three types of computational thinking?

Answer 27

decomposition algorithmic thinking abstraction

Question 28

what is decomposition?

Answer 28

breaking a complex problem down into smaller more manageable problems to solve individually

Question 29

what is algorithmic thinking?

Answer 29

a logical way of getting the problem to the solution

Question 30

what is abstraction?

Answer 30

removing useless details from a problem and focusing on the important parts

Question 31

what is pseudocode?

Answer 31

not an actual programming language but follows a similar structure to roughly read like one shows steps without displaying finer details (syntax)

Question 32

advantages of pseudocode?

Answer 32

quick and easy to write easy to understand for beginners easy to convert into any programming language

Question 33

what is a flowchart?

Answer 33

diagram used to represent data in a program

Question 34

why are flowcharts important?

Answer 34

help programmers develop the most efficient coding because they can clearly see where the data is going to end up
