What is pseudo-code primarily used for?

A visual representation of algorithms
A method of expressing an algorithm textually
A programming language
A debugging tool

The correct answer is: A method of expressing an algorithm textually

Pseudo-code is primarily used as a method of expressing an algorithm textually. It allows programmers and computer scientists to articulate their ideas in a way that is easy to understand without worrying about the syntax of a specific programming language. Pseudo-code uses a simplified and informal style of writing that resembles programming constructs, making it accessible for both humans and machines to interpret the logic behind an algorithm. This form of representation helps in designing algorithms before actual implementation, facilitating discussions and adjustments to the logic as required. By focusing on the logic rather than syntax, it aids in promoting clarity and understanding among team members or those reviewing the algorithm. The other options, such as a visual representation of algorithms, relate more to flowcharts or diagrams which serve different purposes in demonstrating processes. While programming languages have structured syntax and semantics for writing executable code, pseudo-code remains a flexible form of communication devoid of strict rules. Lastly, debugging tools are specifically designed to find and fix errors in code rather than to express algorithms or processes.
