Answer 1

There is. Not much, though. Apart from the differences cited in the answers so far, here are a few points which you could notice right away while you type code and try to execute them.

The difference being that Dev C does not recognize few header files that can be used in Turbo C, such as conio.h. Needless to say, it does not recognize any/all functions/MACROS declared in that header file.Also, there are a few header files which might be having different names. To cite an example, Turbo C has alloc.h, for functions to allocate memory dynamically, while the same header file’s named as malloc.h in Dev C.Another one I know of is that you need to declare a namespace in case of Dev C, but you do not need to do so in case of Turbo C.

These are a few points that I could remember of the top of my head. I’ll keep editing as I remember more! :)
