Help me with this POO please(iii)

There appear the following errors in the "error list":

Error 5 error C2371: 'date::add' : redefinition; different basic types line 25

Error 4 error C2556: 'int date::add(int,date)' : overloaded function differs only by return type from 'date date::add(int,date)' line 25

Error 3 error C4430: missing type specifier - int assumed. Note: C++ does not support default-int line 25

And the algoritm is the following one:

I can't find nothing

You forgot return type on line 25, exactly what your compiler is telling you
