No you're not... you're using DevC++ ... a whole different language. There is no Dev C.
Also you should be aware that compiler and IDE have been abandonware for most of a decade. The compiler is hopelessly out of date and the guy who wrote the IDE is noplace to be found.
I think, you should give serious consideration to getting onto a purely C compiler, C-99 compliant, and a new IDE that is up to date...
I generally suggest Pelles C but there are others you can use.
