Well, what kind of answer do you expect
Love using codeblocks, but my lecturer says we MUST use KDevelop.
If masta say me use KDevelop, me use KDevelop, else masta be angry with me.
ie. is the stuff I write in Codeblocks perfectly compatible with Kdevelop?
Yes and no. Code::Blocks does neither read nor write KDevelop project files.
However, the programs made with Code::Blocks are just as good as if made with KDevelop. You can compile the same sources, link to the same libraries, and get the same executables.
