↓Recommended Follow↓ Everyone knows that computer programming languages are usually divided into three categories: machine language, assembly language, and high-level language. High-level languages need to be translated into machine language to be executed, and there are two ways to translate: compiled and interpreted. Therefore, we generally divide high-level languages into two main categories: compiled languages, … Read more
