Hi,
I am learning C++ from the following C++ website, which has some very
good small examples. For the second Fraction example, which has five
files:
Main.cpp
Fraction.cpp
Fraction.h
msoftcon.cpp
msoftcon.h
,,,,,
A Fraction class that has the ability to add, subtract, multiply,
divide and show various statistics of the fraction. http://www.cplusplus.com/src/
,,,,,,,,,,,,,
When I compile them, MSVC 6++ compiler says:
error C2653: 'Fraction' : is not a class or namespace name
if I put Fraction.h with the .cpp under Source Files category.
If I put Fraction.h under Header Files category, the compiler cannod
find the .h file. I have also tried Settings in the Project menu
without success. I am new to MSVC and C++, could you help me the
settings? Thank you very much. 17  3109

Did you #include "Fraction.h " in Main.cpp and Fraction.cpp?

In Main.cpp, Fraction.h is included.
At the end of Fraction.h, there is:
...........
#include "Fraction.c pp"
#endif
...........
Fraction.cpp seems to be part of declaration of class Fraction
function. I don't know how to solve this. Thanks.

You have to include the header in the source file. Your book should
explain this.

The Fraction.h is included in the main.cpp, see below.
// Allow the integer type to be changed on the fly
#define BIGGEST_INT int
#include <iostream.h// Include C++ input/output functions
#include <stdio.h> // Include C input/output functions
#include <conio.h // Include for pausing the program
#include <stdlib.h // Include C Library functions
#include "Fraction.h " // Includes the Fraction Header File
#include "msoftcon.h " // Allows more functionality to MVC++ console
int main() {
Fraction a;
Fraction b;
Fraction c;
-----
Thanks.
The example is broken, I am afraid you may have to spend some time
reading the code and debugging. It will be a good learning
experience :)

A few tips if you want to learn C++:
1. While there are some websites out there which I would classify as
"not bad" there are none that I would consider "good", and they tend to
be very incomplete (not discussing important topics or only parts of
them). There are a number of good books out there, and if you search the
archives you can find a few that gets recommended often.
2. There are good compilers and there are bad compilers. MSVC++ 6 is one
of the worst, it is simply too old (almost 10 years now) and does not
support many features in C++. If you want to learn you have to get a
newer one, there are a number of gcc bases you can download, and
Microsoft's Visual C++ 2008 Express can also be downloaded for free.

Post a complete, minimal program that demonstrates the problem. That

Hi,
Thank all of you very much. In fact, I am reading the cpp primer of
lippman now. And I have one MS .net V7.1 enen though it is not a
English version. I have downloaded the source code of that book. But I
don't know the best way to use it, i.e. How to compile it as in the
readme.txt file? It says:
--------------------
To use make on a Windows operating system you invoke the command
name "nmake":
## Windows machines
nmake # compiles all the programs
nmake clean # removes all the object files and stackdumps
nmake clobber # removes executable, object and stackdump
files
--------------------
My computer doesn't understand the nmake command. Could you tell me
something about that? Thanks again.

No need to #include the cpp. VC++ will compile the cpp if it is in
your 'source files' section of Solution Explorer (i.e., has been added
to the project).

I am trying to port a simple vector/matrix class library to mingw

Firstly, if I define x to be a CColumnVector, y to be a CRowVector and M
to be a CMatrix (of the right size!) then:
