'''Pseudocode''' is a [[high-level description]] of a [[computer program]] or [[algorithm]]. It uses the structural conventions of a [[programming language]], but is intended for human reading rather than machine reading. Pseudocode omits details that are not essential for human understanding of the algorithm, such as variable declarations and language-specific syntax.

== Purpose ==
The primary purpose of pseudocode is to allow programmers to focus on the logic of the algorithm without being distracted by the syntax of a specific programming language. It serves as an intermediate step between the initial [[algorithm design]] and the final implementation in a programming language.

== Characteristics ==
Pseudocode typically includes:
* [[Control flow]] constructs such as [[if-then-else]] statements, [[loops]], and [[case statements]].
* Descriptions of [[data structures]] and their operations.
* High-level descriptions of [[functions]] and [[procedures]].

Pseudocode does not follow a strict syntax and can vary widely in style. It is often written in a way that is most understandable to the person or team working on the project.

== Example ==
Here is an example of pseudocode for a simple algorithm that finds the maximum value in a list of numbers:

```
Algorithm FindMax
Input: A list of numbers
Output: The maximum number in the list

Begin
max ← list[0]
for each number in list do
if number > max then
max ← number
end if
end for
return max
End
```

== Advantages ==
* '''Clarity''': Pseudocode is easier to read and understand than actual code.
* '''Language-agnostic''': It can be understood by people who are familiar with different programming languages.
* '''Focus on logic''': It helps in focusing on the algorithm's logic without worrying about syntax errors.

== Disadvantages ==
* '''Ambiguity''': Lack of formal syntax can lead to misunderstandings.
* '''Not executable''': Pseudocode cannot be run on a computer, so it must be translated into a programming language.

== Related Concepts ==
* [[Flowchart]]
* [[Algorithm]]
* [[Programming language]]
* [[Software development process]]
