Not a good idea to use doubles in switch statements because they are often inprecice due to the way they are stored in memory. If you really have to use switch instead of that if statement then you should multiply it by 100 then assigned the result to an integer. …

Does it matter how long the delay is? You can use time() to delay for a specific number of seconds. You need one time_t object and set it to the current time. Then enter a loop until the value returned by time() minus the original time equals or exceeds the …

>>what i want to be sure is, after function statements does the allocation space dissapear Yes because you sent the pointer by value and not by reference. You need to send a pointer to a pointer which requires two stars not just one. [code] Allocation(&ucBufr); void Allocation(unsigned char ** ucBufr) …

>>if suppose an device Its "a device" -- see [URL="http://andromeda.rutgers.edu/~jlynch/Writing/a.html"]these grammer rules[/URL] >>is this possible in c? Yes. I think you will have to write a device driver. But you first have to decide what operating system you want to use. MS-Windows you get the [URL="http://www.microsoft.com/whdc/devtools/ddk/default.mspx"]Windows DDK [/URL](Device Driver Kit).

But you can never achieve the oridinal number of digits even when you set the precision to something larger, such as 30. The most cout will display are 15 digits. Probably have to use some other math libraries, maybe boost, for that huge number of digits.

I hate it when teachers teach undefined behavior. :angry: The value of [b]j[/b] will depend on the compiler you are using because the language does not define the behavior of [b]i[/b].

It depends on the compiler and the operating system. You can use an os-independent compiler such as QT which as gui support for *nix, MS-Windows and MAC (others I don't know about). Or you can use os-specific libraries such as win32 api function and MFC class for MS-Windows. There are …

The posted code is not really much of a benchmark program and will not adequately make the test you want with it because the programs are just too trivial.

There are millions of examples because they are frequently used in every-day applications. But a simple introduction might be to write a function that sets all the bytes of a character array to 0. Function prototype might be [code] void clear_array(char* array, int size); [/code]

that's because the loop is wrong. You don't need to use eof() at all [code] while( getline(inData, line) ) { size++; // do other stuff here } [/code]

I'm right handed, but my son is left handed.

Ok you have the function prototype, now create a structure with the required data members and a pointer to the head of the linked list. After that fill in the function you posted with the code. Read some of the other threads here and you will find several similar examples.

see the link near the bottom of [URL="http://www.deitel.com/Books/CPlusPlus/CPlusPlusHowtoProgram6e/tabid/2046/Default.aspx"]this page[/URL]. But I don't know if it is free or not.

[URL="http://www.winprog.org/tutorial/"]Here [/URL]is another popular tutorial

you will need to create a thread that just listens for and receives data from the socket then, when ready, sends a message to the main form thread that the data is ready. I assume QT has mechanism to send and receive messages among threads.

some compilers may support strupr() and strlwr() which convert the entire string, but its not standard. You can easily write such a function yourself.

you have to use os-specific functions. What compiler and what operating system ?

When you add the node to the list in get_input() add it to the tail, not the head. There are at least a couple ways to do that. 1) search for the tail of the list each time you want to add a new node to the tail, or 2) …

please re-read my answer to [URL="http://www.daniweb.com/forums/thread86279.html"]your previous thead here[/URL]. I already answered this question.

The major problem you fase is the operating system you plan to use. MS-Windows and *nix will not permit programs to access the ports directly like that program you posted. Only MS-DOS will permit it. Search some of [URL="http://www.google.com/search?hl=en&q=serial+port+device+drivers"]these google links [/URL]to see it they contain anything useful to you.

Never heard of such a thing -- a printer that prints onto CD's ?? I can only assume you are not referring to a normal paper printer. If not, then you will probably have to contact the manufacturer for a programmers manual and device driver.

line 7: [b]your_name[/b] is a single character and you are attempting to use it as if it were a character array in line 41. Change the declaration in line 7 to be a character array. Or, better yet, since this is a C++ program change it to be std::string class …

whether its working or not -- DO NOT DOWNLOAD THAT FILE. Never ever download a file with *.doc extension because it could contain nasty viruses, worms, etc.

line 10 will cause program crash because no memory has been allocated for [b]name[/b] -- its only a pointer that points to some random memory location. Since this is a c++ program why don't you use std::string class instread? [code] include <fstream> #include <iostream> #include <string> using namespace std; int …

what were the build errors ?

>> temp->name=new_person[]; Is that line 130? You can not assign char arrays like that. You have to use strcpy() instead, like this: [code] #include <cstring> <snip> strcpy(temp->name,new_person); [/code] >> temp->next=Front; >> Front=temp; Circular reference -- is that what you really want ? It results in Front->next == Front, and you …

If you use getline() on line 64 you will avoid the space problem. getline() will read the entire line, then you can separate it into comma-separated tokens. Line 61 is incorrect -- you should avoid using eof() like that because it will cause problems. Use getline() instead, something like this …

Quite often working lots of hours is counter-productive. I recall a couple times I put in 72 hour days and the solution hit me after I finally went home. Working 80-hour weeks often is a bad bad idea because the mind needs a period of rest and relaxation. If your …

you could also make it a structure that contains a union, something like the VARIANT structure that is used frequently by MS-Windows compilers such as VC++ and VB. It looks like this: [code] typedef enum { UNKNOWN = 0, STRING, SHORT, <etc. etc. for each data type } DATATYPE; structure …

If that is the binary representation of the integer, then just typecast it or memcpy() it. [code] char array[some_number]; int n = *(int *)array; or memcpy(&n, array, sizeof(int)); [/code]

use clock() to get the time before starting the algorithm and again afterwards, then subtract the two times. For example [code] clock_t start = clock(); // do something, such as call a function clock_t end = clock(); clock_t diff = end - start; [/code]

The only problems I found were: 1. The structure [b]next[/b] was incorrect [code] typedef struct _nodeList { unsigned int pointCode; struct _nodeList *next; }NodeList; [/code] 2. right_configuration() must return a value.

I wouldn't have lisened to that with or without the lyerics but I agree that AT&T should not have censored out thouse lines. Maybe the webcast editor will get canned or at least disciplined. Don't know if its grounds for a lawsuit or not.

The way I do it is somewhat like Hamrick suggested -- create a project then change the source file(s) as needed. I test out many of the programs posted on the C and C++ boards that way.
