I suspect Dev-C (and Turbo C) are still in use because they have so much academic momentum behind them. Schools (esp. in less prosperous countries) need to eek the most value out of the money they spent so they stick with what they know despite its looming obsolescence. Many teachers are also set in their ways or simply don't want to go through the time and trouble of bringing themselves up-to-speed in order to teach the newest versions.

What will CTRL F5 do? I believe on visual studios it runs the program without debugging it, but hes not on visual studios. I could be wrong but I don't think that works with dev C++ or codeblocks.
