Besides requesting answers to school assignments, it seems that you have
also missed to read the assignment. The request is for a C program, not a
C++ program.

For some reason it seems like you are trying to test code coverage in your
project.

When you run gcov, it will create a file 'sourcefile.gcov' containing the
coverage information for a source file.

Have you set the options -fprofile-arcs and/or -ftest-coverage in your
project?

Is this your homework?=20

Kindly send C++ source codes on the following:
 
Design and develop storage for the hexagonal array of numbers depicted
in Figure 1 below.   Write a program using the C programming language to
implement this data structure and to test (show) that it can store the
numbers 1 through 19 such that the sum of each column and each diagonal
equals 38.  (It is not necessary for rows to sum to 38).
 
Further, you are to invent a notation to describe any element of the
hexagonal array and a direction along any diagonal or column.  The
program must allow the user to use this notation to search for
elements/members of the structure.

I would say that your error is on line 70.

You have made a lot of new lines in the end. However, are you sure that
the last line is empty, and doesn't contain any spaces or tabs? Alas, my
mail program can't show mey white space at end of lines.

Strictly speaking, it's a warning.  An error will prevent it from compiling but
it compiles and runs.

Some errors and warnings within functions are reported with the line number of
the end of the function or the beginning of the function.  The compiler
sometimes cannot determine where the actual problem lies.  Perhaps the problem
actually lies on line 2 (and in stdlib.h) as indicated.  Perhaps the compiler is
confused by other warnings which this program produces.  Turning on all warnings
with "-W -Wall -Wunused -pedantic" compiler options and I get:

C:/WINDOWS/Desktop/states.c: In function `main':
C:/WINDOWS/Desktop/states.c:12: warning: implicit declaration of function

C:/WINDOWS/Desktop/states.c:36: warning: pointer targets in passing arg 1 of

If you fix those warnings you might also correct the missing newline warning.

Also, in Tools > Editor Options > General, make sure that "Keep Trailing Spaces"
is unchecked.  You have eight lines with trailing spaces.  They probably aren't
causing any problems but there's no use in cluttering up your code.

No matter how many times I hit the enter key at the end of this file, I =
keep getting this message:

How can a error that is supposed to occur at the end of the file occur =
in line 2 anyway?  If anyone has any idea what is up here, please tell =
me.

This is not a bug, preprocessor require it.
Look at http://gcc.gnu.org/ml/gcc/2001-07/msg01120.html
Always put one newline on end of file. Probably isn't big problem
for you ?

I'm running the latest devcpp4991setup file, downloaded just a few days ago.  I've gotten the message, however, adding a newline at the end of the offending file stopped the message.  Do you somehow have a hidden or possibly misinterpreted EOF character before the actual end of the file?
 
I'm curious if you used the on-line updating feature.  On my installation, it told me that there where down rev extracted packages in the devcpp4991setup file.   I performed the update of those packages and I had numerous errors, mostly in the C++ section of the include files.  The problem could be isolated to the updated packages whose names started with 'gcc'.  The most important ones, i.e. the core, g++, etc!  Upon un-installing those updated packages and returning to the originals, the problem disappeared.
 
BTW: I did manually delete the devcpp configuration files, and the devcpp folder.

Are you sure that you add new lines in correct file? Warning message may 
be unclear.

if ur working on console app (Main, not WinMain and therefore no

That's it.

Now I got a resource editor (ResEd) and it works great !!!
I can now include all resources to the exe file.
But how do I load, for example, a bitmap from the recource ???

resource file:

picture BITMAP DISCARDABLE "Small.bmp"


main file:

int main(int argc, char **argv) {
  HBITMAP hBM;
  // how to load the resource "picture" into this handle ????
  
}


CU, Acki

Hi,
I want to add bitmap(s) as resources to my project.
But how to do this ???
In the Dev help I found this:

To open the Resource Editor, click on the Project menu, then on "Edit resource file".

But there is no "Edit resource file" in the project menu !!!
There are only 4 menu items in this menu:

New File
Add To Project
Remove from Project
--------------------
Project Options

There is no resource editor !!!!
Or is it a add on, that I have to install first !?!?!

Maybe someone can give me an example, how exactly to add a resource to a project, please 
!?!?!

thx, Acki

Hi Erika,
 
There's lots of random number generators in C and C++.  A good place to start is Google for 'diehard random number generator C++'.  It's a good start as any RNG that can pass the Diehard tests is a good RNG.
 
See Description of the Rand Function in Excel 2003 and Diehard Battery of Tests of Randomness.  On the second link, download the zip file for Windows Software (732KB), http://www.cs.hku.hk/~diehard/cdrom/diehard.zip.  After extracting, open make.txt, which has numerous RNG examples.
 
I know this as I've been working recently on analyzing the capability of the C++ library rand() call.  It totally sucks!  In the alternative, I'm using something like the following, which is however, slow, and I'm looking for a faster version myself that doesn't use floating point!
 
#define TWORAISED16 65536
unsigned int secure_random ( void ) {
/* This method implements a more secure random number generator using the Wichman
   and Hill procedure.  An unsigned integer is returned.
   Alfred P. Reaud, 05/01/05 12:04
   VERIFIED: 05/01/05 12:48
*/
int ix = 0;
int iy = 0;
int iz = 0;
double result = 0;
double rand_f = 0;
double i_part = 0;
 // Create 3 random numbers.
    ix = (171 * rand()) % 30269;
    iy = (172 * rand()) % 30307;
    iz = (170 * rand()) % 30323;
    // Sum them as a double.
    result = ((double)ix / 30269.0) + ((double)iy / 30307.0) + ((double)iz / 30323.0);
    // Make a random number that will be 16 bits wide.
    rand_f = modf(result, &i_part) * TWORAISED16;
    result = modf(rand_f, &i_part);
    return ((unsigned int)i_part) % TWORAISED16;

http://esotic.com/media/EsoticDevDots.zip

The zip contains the modded sample FF project and the compiled
FFDots.dll along with a FFDots.bmp icon for use in the \TZT\SysData
directory (FreeFrame apps can ignore it).  The DLL was compiled with
DevCPP (using MMX and other relevant optimizations).

FFDots supports two input videos but TZT doesn't use ProcessFrameCopy
yet, so could somebody please test that functionality and let me know if
it works correctly?

The effector is 16bit only and will work with ProcessFrame which uses
black for the second layer (works well with chromakey).  There is one
input parameter that changes the mask shape.  There is some potential
for differently sized and shaped masks and other bit-depths (so feel
free to get in there and hack about in the source).  I may update the
source to support 24 and 32 bit unless someone beats me to it.

The Dots effector in TZT tends to be rather fast, and may be equally
speedy in FreeFrame apps.

If I understand you correctly, then all you need to do is this:

char c = i;
// Then as proof...
printf("%c, %d\n",c,c);
printf("%c, %d\n",i,i);

Hope this is what you meant.
