Hi! i'm trying to compile drs_exam.cpp but it yields the following error lines:

I do have the "DRS.h" file on the same folder, which is clearly the file that's causing troubles. I also tried to run "DRS.cpp" but it yields a similar error lines. ('sin definir' means 'not defined').

Thanks a lot for the help!
