Describes how an algorithm works through the use of everyday language.

Advantages/Disadvantages

Advantages	Disadvantages
readable	lack of standards
good for communication between programmers using other languages	few rules
easy to plan, describe and communicate	ambiguity within syntax (e.g. does “For x from 1 to 2” include 2?)
easy to modify and troubleshoot logic
easy to transform into actual code (subjective)

Structured English

Just normal English that describes steps in discrete instructions similar to code:

Set count to 0
Look at each item in price list
if price less than 30
add 1 to count
once complete, display count

Makes use of phrases similar to real code For algorithms there is not a strict set of syntax for pseudocode.

Common but not mandatory conventions include:

indenting blocks
using “End (Block Type)” such as ‘End For’ to end blocks
different operators for assignment and comparison
- common pairs include:
  - ”=” for assignment ”==” for comparison
  - "←" or ”:=” for assignment ”=” for comparison

If cond then
	...
Else
	...
End If

note, does not include the second number, goes [1:10)

For var = 1 to 10 do
	...
End do

Foreach var in list do
	...
End do

While (cond) do 
	...
End do

Repeat until (cond) do
	...
End do
