ok i have a program that has 1 base class and 3 derived classes, all appear to be workin fine, but is there any code that i could put in, that would ask the user what kind of "building" they want to build, and depending on what they put in for their answer, their answer would prompt them for the specs to put in to access the desired building(class)?

N = for normal building(base class)
H = for home (derived class)
S = for school (derived class)
B = for business (derived class)
