I've downloaded 3rd party libraries and I'm trying to link them in with my code but when I use -l<library name> it gives me the error "ld: cannot find -l<lib name>". When I link the libraries explicitly it seems to work okay, ie by entering the full address to the library on the command line or in the makefile. I'm running on Linux, I...

I'm having problems with a program I wrote- when it comes time to output a file, the call to fopen locks up and I have to break the program manually. I've pinpointed the actual stopping point to fopen, but due to my lack of knowledge with gdb, etc., I don't know how to go any further with the debugging from there. I'm running gcc under...

Hi all, A while ago while I was doing a part time c++ course at uni and we where asked to write a code solution to a little problem. The idea being that you can type in either a name or a mark and return all results that match what you typed. The code had to include a doubly linked binary tree. (sorry dont have the original problem...

I am still trying to display 2D arrays with pointers. My prof gave us the prototype void DisplayArray (int (*); where inside the function DisplayArray(array) *(*(array + row) + col) would be the same as array But it does not even accept the prototype. Please help!

When passing an object by value to some function foo(), the copy constructor gets called and inside it i see that the address of the temporary obect is X. but when entering to foo() i see that the address of the temporary object is Y. By looking at the assembly i think that the copiler copies the temporary object to a different location...

Often I have to parse files containing lines of formats like the following: ItemName::1::100 ItemName is a name, 1 and 100 are the min and max values of a range. When I parse such lines I split them into substrings, where "::" is the delimiter. Then I feed them into static methods of classes, that are concerned with:

I have recently installed VC++ 6.0. When I create a new workspace and add .c and .h files, the IDE cannot find a build tool for .h files. Is there any other component that needs to be installed besides the regulare VC++ installation (installed from Visual Studio). Thank You, Ann

1) I would really like to ask this on comp.lang.c#, but no such group exists. However, perhaps someone in one of the above two groups will know the answer and help me out. In my product, I use a variation of a design pattern called "generation gap". In particular, there is library code that knows about certain classes that are user...

Hi, I am using Visual C++ 6.0. I got a "stack overflow" error message when running the program because of a "double array". I have a computer with 1GB memory. Can I extend the memory for the program running? How? Looking forward to hearing from you! Regards,

Why do I get (using Dev-C++) "111," when I should be getting "101" when I enter "5?" I never get a "0" as an output. Can anyone let me know why? Thanks. Steve //----------------------------Code Starts-------------------------------> #include<stack> #include<iostream> using namespace std;
