Here's a brace-enclosed initialiser for a 3D array: int a4 = { { 1, 2, 3, 4, {5, 6, 7 }, }, { {13, 14, 15 }, 17, 18, 19, 20, {21, 22, 23, 24} }}; gcc produces some warnings when compiling this, but sets a4 to this, which is what I'd expect: { { 1 2 3 4 } { 5 6 7 0 } {0 0 0 0 } }

I would like to define a list of parameters, and then pass them to a macro. However, the compiler (gcc) only sees one parameter, rather than expanding the definition. Could anyone suggest a way of making this work (using the preprocessor)? #define MyList 1,2,3,4 #define Sum(a,b,c,d) a+b+c+d x = Sum(MyList);

I'm totally new to C, so this is a question from a total newbie. I know most people write the names in C with underscores, as_in_this_name. But... is it also customary to write them in mixed case, asWithThisName? Or is it a horrible horrible horrible thing to do??

Hello , I have been curious about the speed of 2 version of a matris filling program and got suprised by the results. Actually , I am having Data Structures lecture on university though our professor claimed "using IF structures are costly , so you better use immediate data addressing " so he gave us the pseudo codes that i implemented in...

Right next to K&R2 on my bookshelf is _C Programming: A Modern Approach_ by Professor K.N. King. The second edition of this book is now available. See this URL for details: http://knking.com/books/c2/ I don't think I'm alone among c.l.c. participants in recommending this book (based upon the very good first edition).

Hi I'm using Dev-C++. Here is my sourcecode. /* GETCH.C: This program reads characters from * the keyboard until it receives a 'Y' or 'y'. */ #include <conio.h>

I'm looking for a library that can handle server-side http aspects (parsing headers, doing keepalive, basic auth, etc) without relying too heavily on some underlying event engine -- I want to integrate it into an existing event framework in c/c++. Any suggestions? (searching on "http library c" is an exercise in futility). There must be...

hi all , i am facing a funny problem in C . i am using turbo's compiler - the 16 bit compiler for dos . i made a file maximum.h which contains a function declaration , and includes files such as stdio.h . i then made a maximum.c which contains the definition of the function declared in maximum.h . maximum.c also includes maximum.h . then i...

C is the best because the hackers is most use the C lang

C takes input character by character. I did not find any Standard Library function that can take a word as input. So I want to write one of my own to be used with "Self Referential Structures" of section 6.5 of K&R2. K&R2 has their own version of <getwordwhich, I think, is quite different from what I need: <getwordwill have following...

Hello, I've rewritten a function (greater_or_equal) that relies on implementation-defined behavior and availability of exact-width integers, with the goal of making the new implementation (greater_or_equal2) portable across any platform. What do you think of the new implementation? (Suggestions and comments are welcome.)

Hi Everyone, The following code compiles without any error, int main() { volatile const int a = 10; return(0); };

In the following function, s shouldn't be a pointer costant (array's name)? So why it is legal its increment? Thanks in advance. /* Code starts here */ void chartobyte (char *s) { while (s!=0) { printf ("%d", *s); s++;

Hello, I have written a program in C; this programs uses an external proprietary library. When calling a certain function in the external library, the particular function writes a message to stdout. I am not particularly interested in this message, and would like to silence it - however I do not know how to do it. (I stdout and stderr my...

PURPOSE :: see statement in comments GOT: Segmentation Fault I guess the segfault is sourced in the compile-time warning but I am giving a char* to the function already.

It seems not remember how to compile with gcc a C program in linux (ubuntu) how i have to compile this programme? It seems gcc doesn't find stdio.h.. why is all antiintuitive? Thank you and Good Morning ---------------------------------------------------

Hello friends: I know some people here don't like to answer C++ questions, but I believe this is really about the underlying C code. Anyway I have posted as well to the other group someone suggested ("comp.lang.c++") just in case. I think the problem is that in my C++ class, we were taught to use cin, cout etc. but now I need to use the...

Hello, one of my C compiler (Keil C51) evaluates the constant expression 1<<(1?1:1) < 0x9999 to the value 1. // this returns 0, much to my surprise unsigned char bug4_a(void) { return 1<<(1?1:1) < 0x9999;
