It is one of the important senior software engineer coding interview questions. In Structured English, words or sentences that have native English sounds and meanings are used to describe the structure of a program module instead of programming language instructions and keywords, while in Pseudo Code, native English words or phrases are used to describe parts of a program module. Pseudo Code and structured English are two different ways to write code. Pseudo Code is a way of writing down the logic of a program in a way that people can understand. It is similar to natural language but has a more technical focus. Structured English is a method of writing code that is easier to read than pseudo code and contains rules that help you avoid making mistakes.
