Headers and source file

gduong (26)
I am trying to learn how to use headers and source file. I have been reading this http://www.cplusplus.com/forum/articles/10627/. My error is:

Error 1 error LNK2019: unresolved external symbol "public: __thiscall Car::Car(void)" (??0Car@@QAE@XZ) referenced in function _main C:\Users\George\documents\visual studio 2013\Projects\Chapter13\Chapter13\main.obj Chapter13

also

Error 2 error LNK1120: 1 unresolved externals C:\Users\George\documents\visual studio 2013\Projects\Chapter13\Debug\Chapter13.exe 1 1 Chapter13
