1.)


When you declare house::house(), you should write "house();" not "house:". Using a colon instead of a semicolon makes the compiler expect to see an initialization list.





2.)


When you define house::house(), you should write "house::house", not "house:house", because "house::house" is the fully-qualified name of the function, whereas "house:house" is simply an illegal construct.





3.)


When you give an initialization list for house::house, you should not terminate the initialization list in a semicolon. The initialization list is terminated by the open brace.





4.)


You appear to be missing the definitions of a number of other functions.





5.)


You should define a copy constructor "house::house(const house%26amp;)", and then you can simply use the default assignment operator instead of set_value.
