Re: your mail
Good $daytime, To do some programming I use for instance EMACS. When I'm done I exit EMACS and run GCC and then run the program to see if it does the thing I want it to do. This procedure is time consuming and not eficient. There is no need to exit any editor. If you're running X windows, you have both emacs and xterm at the same time. If not, you may open one console for editor and another for your shell. But there's a better way! Try `M-x compile' -- emacs will read gcc output in another buffer. Clicking mouse-2 over error message will bring you to the line in question -- no need for extra IDE. Is there any compiler/editor/debugger-package anvailable from the internet? Or am I missing something here? I've noticed that MC has an edit feature which shows source code using different colours. I find this very helpfull. There are many IDE-like products. To see a few, look at freshmeat.net appindex, section 'Development'. Well, if you're looking forward to "attend the Church of Emacs" :), try `M-x font-lock-mode'. Emacs has nice syntax highlighting -- and knows C/C++ to some extent. Hope this helps...

Re: your mail
I don't use emacs much but I use vim. One way you can do what you're trying to do is by first making a Makefile (learn how to make them :-]) then, has to be in the same directory editing your source file with vim then you'd just have to hit escape then colon (:) and type make, after that you can type ":make run" (if you've made your Makefile well). --- Wei Weng [EMAIL PROTECTED] wrote: You can always use shell command from emacs.

Re: your mail
go out to www.mamma.com and search for "ddd" It should be on ftp.lame.org, also. ddd uses gdb, and requires X windows. It provides superior source level debugging. you may also use xxgdb, or simply gdb to debug programs at the source level. you must compile and link with the -g option to do this. bug On Wed, 31 Mar 1999, Darius Blaszijk wrote: Hi all, Having my latest problems using DOS/WINDOWS, I decided to start programming under LINUX.

C isn't a simple language to use. It was intended to be efficient and flexible in the hands of experienced programmers. Ease of learning wasn't really a consideration. Reading C programming lists (e.g. this one) and newsgroups (e.g. comp.lang.c) tends to indicate that many people overlook certain fundamental issues in the way that C works. A particular example is C's handling of pointers, e.g. the ways in which they are similar to arrays and the ways in which they differ. Basically, I don't think that C is the kind of language which you can learn purely from a mixture of examples, asking questions, reading reference material, and trial-and-error. I do think that you *need* to read a book which covers the language in detail first. -- Glynn Clements [EMAIL PROTECTED]

But it ignores the fact that original poster clearly WAS TRYING to learn C. Did you notice the comment at the top about how it was an exercise from page 112 in a textbook? That's why I gave him a hint on his problem but didn't correct the other flaws. We can't be doing people's homework for them.

what am i doing wrong here. it compiles and works but after you enter in
the first value it just stops. /*

{
printf( "\nenter x1: " );

x1 = 'E';
return x1;
}
return x1;

1. This (and the x2/y1/y2 versions) won't work. C uses call-by-value,
not call-by-reference. You would use either
float read_x1( void )
or
void read_x1(float *px1)
instead.
2. there isn't any point having four (nearly) identical functions,
which differ only in the prompt. Use something like:
float read_float(const char *prompt)
{
float x;
printf( "enter %s: ", prompt );
fflush( stdout );
if ( scanf( "%f" , x ) != 1 )
{
fprintf( stderr, "Failed to read entered number\n" );
return NAN; /* IEEE Not-A-Number */
}
return x;
}
3. However, the reason why your program is failing is that you are
unconditionally returning after the call to read_x1(). The indentation
doesn't match the presence of the semicolons; you wrote:
if ( ( j = read_x1( x1 ) ) == 'E' );
return EXIT_FAILURE;
but it would be more accurate to write
if ( ( j = read_x1( x1 ) ) == 'E' )
;
return EXIT_FAILURE;
I.e. you are conditionally executing an empty statement, then
unconditionally returning. Remove the semicolon, i.e.
if ( ( j = read_x1( x1 ) ) == 'E' ) /* no semicolon here */
return EXIT_FAILURE;
4. This has nothing to do with Linux. The above is all vanilla ANSI C,
and would apply equally to MS-DOS or VMS.
5. I think that you need to get a book on C.
