In an Integrated Development Environment (IDE), where is the source code written and edited?

In an Integrated Development Environment (IDE), the source code is written and edited in the code editor. The code editor is a specialized text editor that provides features to facilitate coding, such as syntax highlighting, auto-indentation, and code completion. These features help developers to write code more efficiently and with fewer errors.

Other components of the IDE, such as the compiler and debugger, serve different purposes. The compiler translates the written code into machine code that the computer can execute, while the debugger helps identify and fix errors in the code. The terminal can be used for various command-line operations but is not the primary interface for writing and editing source code. Hence, the code editor is specifically designed for that role within the IDE.
