Lately I've been working on C++ and have gotten ok with it.  Right now I'm working on a program that will calculate the Volume of a Rectangular Prism, Cylinder and Pyramid using functions.  Everything seems to run well exept when I compile it, it gives me this error message.

Quote
38 | C:\Documents and Settings\Owner\My Documents\C++\project\VolumeType.cpp:14 | funcCubeVolume.cpp: No such file or directory.

On line 38 is this piece of code.

Code: [Select]
#include <funcCubeVolume.cpp>
I can't quite figure it out.  Also, this pic may or may not help.

Help is appreciated.  If you need more information, just ask for it.

Why are you including .cpps?
I was always told never to and you don't need it anyway as Dev-C++ compiles them all and then sticks them all into one executable.
The idea is that you have a header with the function definition ie:
Code: [Select]
double cuboidVolume(double a, double b, doublec);

And then you include that in both the cuboidVolume.cpp and main.cpp, and as long as you have inclusion guards on it (I assume you know how to do that). It will compile fine.

I don't see why you would include a .cpp file either...
but...
Code: [Select]
#include "funcCubeVolume.cpp" ?

As said above, you really should create a header file, including cpp files is a really bad idea <_<. Also you shouldnt use the <> tokens when including a local source file you should use "" (<> looks for files in the windows folder, such as Windows.h, GL\OpenGL.h...etc)

Always use header files, always use quotation marks.

Custom:

#include "bmpRun.h"

Predefined with Windows:

#include <windows.h>

Just a note in general though, if you get a case like this again (where it says it can't find a file that DOES exist), and it isn't because of the .cpp or <> as opposed to "" thing, if you go build -> rebuild solution, it relinks the files if they somehow got de-linked. Or, deleting your debug folder sometimes does the trick too. (These wouldn't work in this case prolly, but they work in similar cases.)

yea, common mistake I think with newer people (i've done it  A LOT in the past few months).  Just don't use #include on cpp files.
