While attempting to learn C++ through DOS (all attempts at windows programming have exasperated me to tears), I pulled out Borland C++ 4.52, set my TargetExpert to a standard DOS application and tried to call some simple functions from graphics.h. None of the functions in graphics.h are recognized by the compiler. For example, rectangle(1,2,3,4) gives the error "undefined symbol _rectangle() in [current module]". But if I call the function with the wrong number of parameters (rectangle(1,2,3,4,5) it states that it knows I've used the wrong number of parameters.
What have I done wrong /now/?
