Q
What is pseudocode?
A
- Written statements in english which resembles a programming language to describe the algorithm
- No standard notation
- Uses indentation to show instruction dependency on a selection or repetition
9

A
10
Q
How would you represent functions like maths in pseudocode?
A
- Do not call programming methods
- Instead describe the function of those methods

Q
What are the rules of pseudocode?
A
Pseudocode must be
- Correct
- Consistent
- Written in a form that can be understood by teammates
- Clear and unambiguous
- Can be implemented on the intended systems
