RE: [Dev-C++] Newbie: Linker Errors

if these are the messages you are getting:
compile.cpp: In member function `void DigitalTime::advance(int, int)':
compile.cpp:56: `hourAdded' undeclared (first use this function)
compile.cpp:56: (Each undeclared identifier is reported only once for
each=20
   function it appears in.)
compile.cpp: In function `std::ostream& operator<<(std::ostream&, const=20
   DigitalTime&)':
compile.cpp:63: `theOjbect' undeclared (first use this function)
compile.cpp: In function `std::istream& operator>>(std::istream&,=20
   DigitalTime&)':
compile.cpp:73: `readHours' undeclared (first use this function)
compile.cpp: In function `void readHour(std::istream&, int&)':
compile.cpp:127: `thehour' undeclared (first use this function)
make.exe: *** [compile.o] Error 1 Execution terminated

Then you need to declare each of these missing values( or spell them as
they have been declared ).
    hour =3D (hour + hourAdded)%24; should hourAdded be hoursAdded per
void DigitalTime::advance(int hoursAdded, int minutesAdded)

if (theOjbect.minute < 10) -> as above spelling counts

readHours(ins, theObject.hour); -> ditto

readHours(ins, theObject.hour); -> ditto
reid
