#defines are preprocessor and get expanded at compile time.

Hi All, I have a query with #defines in C. There is a -E compiler option which would expand the #define at compile time and create an intermediate file and create the object file for the same. But normally do #defines get expanded at compile time or at run time. My feeling it gets expanded at run time and not in the object code. Also inline functions inline the code which means these functions will have the code embedded in the object code. This is not the case for #defines which get expanded at runtime . Please clarify .
