Error C2374

lolp1 · #1 25-May-2008, 09:10

I don't have very much experience at all in C++.

I am using c++ Visual Studio 6.0.

I have this source code and when I try to compile it I get 42 errors and 20 warnings, could someone here fix them for me or help me fix them so that it will compile successfully?

Thanks a lot!

Here is the file, rapidshare.com

Here is the error log:

WIthout seeing the code, all anyone here can do is repeat what is already stated in the warnings & errors you already have in front of you. In particular, it looks like you are having repeated problems with redefining specific variable names within the same scope.

Perhaps what you need to do is break the problem down mentally into something more manageable. Take the first error & study the code which it indicates. Since you have repeated redefined variable name problems, look within the same scope & find where other variables are defined with the same name. Systematically resolve these problems one after the other.
Most compilers will correctly identify the first errors correctly. As compilers work their way through more errant code, they tend to begin flagging all kinds of things as errors when in fact they weren't. Because of this, resolve the first few errors followed by recompiling again. It is not uncommon to fix just a few errors & find out that all other errors vaporized. If I had to guess, I suspect that some of the assignment & Boolean operator errors seen in the output presented may go away once you have resolved some of these duplicate symbol problems.

In general, treat debugging as an exercise in divide & conquer. Break the overall situation into smaller more manageable pieces & attach them one after another.

Oh here is the source, it got filtered somehow

Speaking only for myself, I will flatly say that I have no intention of going to a questionable site and downloading a questionable zip file and trying to debug your program for you. Sorry. Maybe someone else is a little more adventuresome...

Now, if you are not familiar with C++ and you are using an old, buggy compiler like Visual C++ version 6, and you are having problems, I don't know whether anyone can really help.

However...

I know for a fact that programs like the following give the "multiple initialization" error with Visual C++ version 6. Try it on your system:

CPP / C++ / C Code:

#include <iostream>
using namespace std;

int main()
{
    for (int i = 0; i < 5; i++) {
        cout << "Loop1: i = " << i << endl;
    }
    cout << endl;
    for (int i = 4; i >= 0; i--) {
        cout << "Loop2: i = " << i << endl;
    }
    return 0;
}

This is Standard C++, and should give an output that looks like:

Code:

Loop1: i = 0
Loop1: i = 1
Loop1: i = 2
Loop1: i = 3
Loop1: i = 4

Loop2: i = 4
Loop2: i = 3
Loop2: i = 2
Loop2: i = 1
Loop2: i = 0

Later versions of Microsoft compilers have no problems with this code. Recent Borland compilers (I don't know and don't care about Turbo C versions 1, 2, or 3) have no problems with this. GNU compilers have no problems with this.

Bottom line: If you are a little familiar with C++, then it shouldn't be difficult to modify the source so that variables are all declared at the beginning of a block (beginning of a function for example, like we did in C programs before the '99 standard). If you aren't even that familiar with C++, then I think you might be better off learning on simple programs before tackling this project.

I, personally, would favor downloading a current compiler. Free ones are available from Microsoft, Borland, and GNU.

Anyhow, after you resolve the multiple definitions, there still may be some other problems. You won't know until you get past the ones that I told you about. Sometimes fixing one type of problem fixes other messages as well.

If you aren't even familiar enough with C++ to go through and collect variable declarations at the beginning of each function, I'm not sure that trying to compile OPC (Other People's Code) is the best and most efficient learning experience, but I wish you luck.

Regards,

Dave
