See man the difference b/w turbo and dev is that one is in DOS (former) and the other one in Windows (latter) ie all handles, values etc are returned by OS.
And Dev C++ is a project by free software foundation.
The difference in syntax is.
1. conio.h and graphics.h is not available in dev c++, but if u still want it u can get it( serach on their forum for this, u'll surely get it).
2. use <iostream> instead of <iostream.h>
3. use int main in place of void main and retuen 0 before completing thebraces ( {} )
4. use system("pause") statement at the end...its like conio.h....and there are few other differences which u can figure out later.
Obviously, None of the conio and graphics functions will work in dev C++ unless u get their header files.
BYE..PM me if u want to clarify anything
