What is Free IDE Software?

Integrated Development Environments (IDEs) are software programs which provide an integrated environment for a programmer to develop their code. The IDEs usually provide tools such as a text editor, compiler, and debugger. They are designed to increase productivity by allowing programmers to work on multiple components of their project in the same environment. IDEs also typically offer features such as syntax highlighting, suggestions for identifiers, and auto-completion that aid in coding accuracy.
