QuestionWhere can I write pseudocode?Community AnswerWhen you start jotting it down it can be anything from a notepad to a napkin or a dedicated writing application like Word or Google Docs. Once you start detailing your pseudocode I recommend switching over to a plain text/raw text (.txt) application such as Notepad, TextEdit, WordPad, and then begin translating it to actual code gradually. It's very important to remember that a computer CANNOT execute code written in a formatted document file, such as .doc or .docx, pdf. They can only interpret .txt plain text, made into something like a .jar, .class, etc (developer file formats). You cannot run code with just raw text. Remember to make it a dev file first.

QuestionIs pseudocode and algorithm the same, or different?Graham TrottCommunity AnswerDifferent. An algorithm is a set of steps to perform a given function; pseudocode is just one way of describing those steps. The steps can be expressed in a conventional programming language or in pseudocode. The former will actually run; the latter will not until translated into computer code. Unless, that is, someone writes a compiler to handle your pseudocode. That's not as silly as it may sound; languages like Apple's HyperTalk closely resemble pseudocode.
