Thanks guys I also have another question do you know how to fix the host application to run a library problem that I am coming across? If you do that would be great and I'm talking like any methods that I should do the fix it or something along those lines.
Please give more information about what IDE you are using and how you have setup your solution/projects.
If you have two separate projects, one for the library and one for the test code, look at which one is set to be the 'startup project' in the IDE. If it is the library change it to the test one.
That is an example. If you want to use functions and/or objects that are provided in a library, you just call them from your programme, #include any headers that come with the library, and link to the library at link time.
As an aside, this is one of the reasons why I advocate not giving new programmers IDEs. We end up thrashing around making the IDE work instead of teaching them how to programme. Obviously other opinions differ. :)
