Hello,
I've got a problem with the term 'solution'.
I created for each example in the book a different directory (from Project0001 to Project 0050 now) and I placed the first example of the downloaded examples in Project0001 (this built pretty straightforward).
Now comes the problem: I placed the second example (Ex1_02.cpp) in folder Project0002 and now VC++ fails to build the program.
What am I doing wrong?
(The code is right, no errors)

Hi,

I'm not great at C++ and I don't have a compiler on this machine, but I suspect you have put both code files in the same C++ project and they are conflicting with each other.

Although you have put the files into a different directory, they are still part of the same application and the compiler will build them into 1 exe file. You need to create a new C++ project for each example. The simplest way is to create a new solution each time you do an example.

For now, the easiest way to think of things is:

• Solution: A collection of one or more projects. If an application will contain lots of DLLs or EXEs, this lets you see the code for all of them in one place.
• Project: Creates 1 DLL or EXE file.
• Folder: Helps you organise your code. The compiler doesn't care about this tho - it just looks at what is in the project.

Was this solved?

If not could you copy the response from the output window when you try to compile?
