Example 2: what is an IDE

An integrated development environment (IDE) 
is software for building applications that combines 
common developer tools into a single graphical user interface (GUI). 

An IDE typically consists of:
Source code EDITOR:
- syntax highlighting
- language specific auto-completion
- checking for bugs as code is being written.
AUTOMTION: 
simple, repeatable tasks as 
creating a local build 
compiling, packaging, running automated tests.
DEBUGGER: 
testing programs
display the location of a bug in the original code.
