The editor enables programmers to read code easily through color schemes, insert indents on new lines automatically, pick the appropriate coding style, and avail context-aware code completion suggestions. In comparison, IDE provides more features but code editors are fast and comes in small sizes. It is considered portable because it is a cross-platform language. It only takes a minute to sign up. These also allow developers to write the code for developing any software and can even save small text files for the code. XML stands for eXtensible Markup Language. They're great for writing a wide variety of reusable code that can work in a lot of different contexts. With the purpose in mind of just showing you the mechanics behind building C++ extensions you will create a very basic math library.
