Hi, I am having trouble understanding how the 'const' modifier affects the 'left-right' rule when deciphering c-declarations: const int *x; // x is a pointer to a 'const int' int const *x; // ?? these are the same, right? in this case the basetype is 'const int' ? int * const x = 0; // x is a const-pointer to int

do you know any links where i can find puzzles, like the 8 queens problem? (I'm not intrested in the solution, only for puzzle...)

Hello, this is a test case of something I just can't explain myself: //////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// #include <list> typedef void (*registerfunc)(); class CMgr {

Why the following code compiles in C++, it is overloading a funciton "x" with 2 different return value (one is int, one is void). Is that legal? Thanks. class Test1 { public: Test1(); virtual ~Test1();

Hi there, I am having the following problem: I have the following class: class reachGraphState { protected: /* ... some stuff .... */ public:

hello all, I have a C++ file, which calls a c++ library which returns a Vector<Struct> My C++ File is invoked via a Jni call... Instead of parsing the vector & returning an Object array back to my Java Class, can i return the vector itself ??... or Can I pass a refrence to a Vector from my Java class to my C++

Hi, I've refreshed my Ternary search tree implementation at http://abc.se/~re/code/tst/ It should now be usable. It compiles cleanly with Comeau's online compiler, g++ 3.4.3, and MSVC 7.1. Some tests are included (some tests not portable). There are wrapper classes that will work as (nearly) drop-in replacements for set, map, multiset,...

Hi, If I define a const stl vector attribute in my class, class A { public: A(); private: const vector<int> v; };

This is probably just newbie silliness to all you c++ gurus but I just noticed an interesting compiler warning today while compiling this function: const std::string& someclass::somemethod() { return "This is a string literal"; } The compiler warned me that an address of a local variable or a

Hi, I'm learning C-programming. I have a program which I would like to modify so it takes arguments from the commandline. Let call the program: program.exe. Could somebody shortly explain how I get this behaviour: C:>program -help or C:>program -h printf("\nBla. bla. Here is some help and arguments\n").... etc.

Hello, I compiled some source with the new Visual Studio 2005 C++ compiler and got some unexpected error. Most other compilers (incl. VC6, gcc) are fine with the code. Extracted sample: class FriendClass { class MemberClass

How come I an not use class initialization to initalize inherited attributes? i have this code: B::B(A& a) { x = a.x; y = a.y; } class A {

In the following code: class Foo { public: Foo(string& foo, string& bar) : foo(foo), bar(bar) {} private: string foo, bar; }; Is this argument naming a common practice or considered evil? Or even

Consider the below code: int main(void) { class inner {}; friend class inner; /* what does this signify???? */ return 0; }

Hi group, I am looking for source code for linear programming in simplex method. Please send any relevant code to me urgently in C,C++ or JAVA.

I have a qestion about reading file in C++. How can I read a file line by line (i.e. putting a line ends wtih \n in a string) I tried the following, it does read the file, but it does not read it line by line. ifstream infile (fileName.c_str()); string buffer;

Hi, Could anyone direct me to a very good 1D DCT Implementation in C/C++ My data is in sets of 8 numbers. Thanks a ton, Soumyadip.

I have a design type of quesiton. What is the advantages of using accessor (a getter/setter method) instead of making the attribute 'public'? If a class has public accessor (a getter/setter method) for its attribute, why not just make the attribute 'public'? It requires less code/typing. Or is there something I am missing? Thank you.

Could someone give me a quick algorithm or c code help that searchs a linked list and updates the value field of a linked list with the following structure. struct Val { char type; int length; char value; } Values;

I am implementing a double-linkedlist in C. I have defined some pointers that points to different locations in my list. Before using the list I will initialize these pointers and when I call insert/delete etc they will be changed. Instead of giving each funtion these pointers as argumentens I was wondering if it was possible to place them i...

I have this program and I need to work on the test portion, which tests if a Val is in the list. It returns false no matter what could you look at the part and see what might need to be done to fix it. It reads in the file and sorts out the files into the four different lists.

Dear All, I am new to c++ and when write below code that try to call copy constructor in "=" operator overloading, it can not compile. Can anyone point out for me the reason? thanks !! class AA {

Is it better to have multiple if statements rather having multiple conditions in single if statement ? which one is better: if (cond1 || cond2 && (cond3 || cond4) || cond5) if(cond1 || cond5) if(cond2 && (cond3 || cond4)) this is an example, there might be more conditions.

Hi I use a define like this to search an element in a linked list #define SEARCH_NEXT( _Block, _Queue) { _Block = _Block->##_Queue.pNext; }
