Linked Lists Help.

OLittleO (54)
I am trying to have a print function and there is just something I am not getting with my client code. It seems all my other files are fine. Frankly I have been going at this for several hours now and I probably just burned out, but I would like get this to work before I call it day. Here are my errors and code.

LinkedLists\main.cpp|3|error: ContactList.h: No such file or directory|
LinkedLists\main.cpp|4|error: Contact.h: No such file or directory|
LinkedLists\main.cpp||In function 'int main()':|
LinkedLists\main.cpp|10|error: 'ContactList' was not declared in this scope|
LinkedLists\main.cpp|10|error: 'cl1' was not declared in this scope|
LinkedLists\main.cpp|10|error: expected type-specifier before 'ContactList'|
LinkedLists\main.cpp|10|error: expected ';' before 'ContactList'|
||=== Build finished: 6 errors, 0 warnings ===|

This is probably the most important of your error messages and it tells you exactly what is wrong.
LinkedLists\main.cpp|3|error: ContactList.h: No such file or directory|
Where is your ContactList.h file located, the compiler can't find it in the normal places.

The same with this one:
LinkedLists\main.cpp|4|error: Contact.h: No such file or directory|

Are they located in the same directory as the file containing your main() function?

They are all located on my desktop in folder called linked lists. I am using code blocks add I added the files recursively. Should I have done it a different way?
jlb (4973)
I'm not a Windows user, but why did you place these files on you desktop instead of the directory where your project was created?

OLittleO (54)
well what I did was i created each file first. Then I created a project and add the files to the project.

Despite "adding" the projects with Code::Blocks add files function, the source and header files themselves should still be in the same folder. I had the same problem once. :\
OLittleO (54)
Yeah that was the problem thanks guys. Just sometimes these programs lol
