The topic comes from a question: Would you rather wait for the results of a quicksort, a linear search, or a bubble sort on a 200000 element array? 1Quicksort 2Linear Search 3Bubble Sort The answer is 2Linear Search

Recently we had poor Mr "teapot" that was horrified at the heresy of lcc-win of accepting // comments. C is a nice language, and you can do anything with it, inclusive a program that transforms // comments into well behaved /* ... */ ones... ------------------------------------------------cut here /*

OK, I have this piece of code: void method(void* parameter) { 1: struct Data* dataOfReference=(struct Data*)parameter; 2: Info tmpInfo=(*dataOfReference).payload.data; 3: char* message; .... }

struct abc { int x; char y; }; struct xyz { struct abc p; //LINE 1 int q;

Hello all, I am trying to understand in detail the correct wording to use in C for teaching purposes. For the example: int foo(int x, int y) { int k; ... return k; }

I need to be able generate C-style declarations from a specification (I call it a typespec) in left-to-right form (as it might be expressed in English). What is the algorithm, or where can I found the algorithm, to do so? I have looked at some code in K&R2 p126 ('undcl'), but that works on character input (I already have the typespec in...

Hello What is the best IDE to use for C/C++ languages? Previously I used "turbo c" compiler on Windows XP. But now I switched to Windows Vista where I cant use it. I tried to setup CDT eclipse but could not compile C program. Can somebody please tell me which IDE is best and from where to

Suppose I have this code: unsigned short svalue; unsigned char hibyte, lobyte; svalue = 0xABCD; hibyte = (svalue >8) & 0xFF; lobyte = svalue & 0xFF;

thx

K & R 5-5 asks for a strncat function ( concat n characters of t); void mystrncat(char *s, char *t, int n) { while ( *s++); /* find end of s */ /* <<<<< 1 */ /* stops at '\0' */ /* <<<<<2 */

WWDPD - Before posting to c.l.c, I try to ask the question ``What would Dan Pop do?''. With that in mind, I'm certain that Dan would never begin a message with a salutation such as ``Hi'', ``Hey'' or ``Hello''. As a oldtimer in this group, I don't recall usage of such salutations by Dan or anyone else for that matter back in the 1990's. I...

My problem is that it's not only short ints that I have to accomodate, but also the occasional long; I'd like to have a uniform handling of these operations. Also, I'm not sure if the way I found to "deserialize" these values is...

I'm working with a microcontroller at the moment that has a single instruction for clearing a bit in a byte. I started off with the following line of code: x &= ~0x8u; /* Clear the 4th bit */ But then I changed it to the following because I thought I might get more efficient assembler out of it:

To increase the performance, how to change the / operator with bitwise operators? for ex: 25/5, 225/25 or 25/3 or any division, but I am not bothered of any remainder.

This program follows from the section 6.5 of K&R2 where authors created a doubly-linked list using a binary-tree based approach. The only thing I have rewritten myself is the getword function. I am using it because there are many concepts involved in this program that I want to understand like: 1.) degree of efficiency of this program as...

I've been trying to use _kbhit() but it didn't do what I thought it would from books, "Detects whether a keypress is available for reading." Herbert Schildt says, "If the user has pressed a key, this function returns true(non-0), but does not read the character. If no keystroke is pending, kbhit() returns false (0)." Here is the test...

How I (recursive) can reverse and print a string (as simple as possible)? I tried with the following code, but it doesn't work. Thanks in advance to everbody. /* Code starts here */ #include <stdio.h> void invstr(char* s) {

I had asked this in comp.lang.c++ with out any answers that would actually work, so I'm hoping someone here may know a way. I am calling C library functions that want to output to stdout. I need to capture this to memory for use internally inside the program without modifying the library calls that actually do the output. This is for the...
