This is my 1st year B-tech Seminar topic.Can anyone plaese give me someone please give me some points for this????

Hi, I am having trouble with a member function pointer. It sees to give me the followign error Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. It only seems to give me problems if I use the friend class declaration

Here is my problem: suppose there are, say, five events with these probabilities: event1 0.7 event2 0.1 event3 0.1 event4 0.05 event5 0.05 Note that sum of the probabilities is 1.0. I would like a function that

GCC in linux 2.6.8 pthread_mutex_lock.c:78: __pthread_mutex_lock: Assertion `mutex->__data.__owner == 0' failed. Aborted

Hi, I have a doubt of storing static variables in memory.I think static,global variables are stored in the same location.Static,Gloabal variables are stored in HEAP .Can anybody explain me the storage area of all type variable in memory Rgds, Mani

Hi, 1) I'm making a container for string pointers... set<string*> strSet; strSet.insert(...); // insert some strings ....

Hi, I have 2 list of class A, is there a STL algorithm which find out if there is equal element between them (using == operator of A)? Thank you.

Hi, When it comes to code portability, most people would think C is a better choice then C++. That was probably true 5 or 10 years ago, but how about today? Are there still many platforms or devices that have no good C++ compiler? C++ offers a lot more then C, would you use it to build a new cross-platform project that will support a...

I'm working on a project for my c++ class and I am having trouble comparing one string to two others using the or operator. It looks something like this: if(answer3 == answer1 || answer2) Is there another command I need to through in there or should I do it a completely different way? Any suggestions would be most appreciated.

I'm trying to get average value. My first attempt is: #include <...> template <typename T> struct avg : public unary_function<T, void> { T sum, count; avg() : sum(0), count(0) {} void operator()(T value) { sum+=value; ++count; }

In the article http://en.wikipedia.org/wiki/Type_safety it is written as The archetypal type-unsafe language is C because (for example) it is possible for an integer to be viewed as a function pointer, which can then be jumped to and executed, causing errors such as segmentation faults, or (more insidiously) silent failures. Even...

Anyone help me i will very happy: I write my code for dos in bc3.1 and have 700kB exe file . How can i use 16-bit protected mode and run my exe filr.

I was just thinking about the virtues of C vs. C++ wrt. ADT/generic programming. The biggest complaint about writing container libraries for ADTs is that void * offers no type safety. Does it really have to be this way? Couldn't you for instance track an object's accesses with void pointers and ensure they are used consistently across...

hi #i am looking for random number generator by c thanx

i'm a newbie for c programming. Anyone can tell me what the meaning of '<<', '>>', '&' and ' | '?

PROBLEM STATEMENT: I want to calculate the byte offset of a field with a struct at compile time without instantiating an instance of the struct at runtime AND I want to do this in an ANSI standard compliant fashion. DISCUSSION: Below is a sample program that demonstrates my solution. My questions are:

I ran across this code from a statistics library. The header source code was not available. long double __declspec(naked) poisson_distribution(int k,long double m) { } long double pdtrl(int k,long double m ) { long double v;

I thought (as they're in c99) that flexible arrays were there for a number of reasons - but I also thought they'd be great for stepping into structures (say) that were aligned in memory after (say) a header struct, e.g.: struct element { int a; int b; };

Can I use printf inside a variadic function that I am writing? Like: void print(const char * format,...) { va_list va; va_start(va, format); char buffer; // yeah, I know... vsprintf(buffer, format, va);

Hi all, Let me describe the problem. I've a header file util.h which contains the following: #ifndef UTIL_H_ #define UTIL_H_ const char DEF_TITLE = "My Title"; int num_chars(int num);

I am a bit uncertain that this is a good use of pointers: int *ip; ip = malloc(sizeof(int)); *ip = 22; Is there any problems with this declaration and would it survive a function that returns, if I make the function return a pointer to an int??

How would I go about sorting this structure by title? typedef struct { char author; char title; char code; int hold; int loan; } LIBRARY;

Hi, I'm working on an implementation of the CORDIC algorithm for a library of functions. One of the benefits of the CORDIC algorithm is that you can implement it with simple additions of numbers and division of (doubles) by powers of two. However, there doesn't seem to be any mechanism in the C/C++ language to direct the compiler to do...

http://www.rafb.net/paste/results/fTQgRW16.html Here's my program so far. This is what I'm trying to do: http://contest-cemc.uwaterloo.ca/ccc/2005/senior/phone.pdf So far it works fine. The only problem is that I'm not sure how to input data, s1, into the program. The second thing that I'm not sure how to input the variable into the function....

Hi, Can you please tell me what is the guideline in Putting implmentation in .h files? I see examples where they put the implementation of getter/setting in the .h files where funcitons is > 10 lines of code are put in .cpp file. Is that the guideline?
