• The code editor is the main part of an IDE, it's where the code is written. Most code editors will have line numbering and auto-colour coding. Good code editors will also have other automatic features like auto-correct, auto indentation and auto-complete
• Error diagnostics and debugging tools help to find and fix errors in a program- they'll tell you the location of the error and often suggest ways to fix it
• A run-time environment allows the code to be run quickly within the IDE - this is done using a start or run button. The run-time environment can also help to identify logic errors in the program as the programmer can see which part of the code is running when the error occurs
• A translator (compiler, interpreter or both) which allows source code to be understood by the computer. If the IDE has both then you can take advantage of each translator's best features
