I'm trying to use NetBeans 6.8 on an AIX OS for C++ development. I continue getting an error message for: using namespace std; even after adding the includes for the STL via options -- c/c++ -- code assistance The error says: "Unable to resolve identifier std" Is this a bug in the Netbeans 6.8 AIX version? Or am I missing som...
Why this code does not compile (Cygwin)? #include <vector> template <class Ttile> class Tilemap { typedef std::vector< Ttile > TtileRow; typedef std::vector< TtileRow > TtileMap; typedef TtileMap::iterator TtileMapIterator; // error here }; error: type std::vector<std::vector<Ttile, std::allocator<_CharT> >, std::alloc...
I have the following method which is not capturing anything from the user.If I input New Band for the artist name, it only captures "New" and it lefts out "Band". If I use cin.getline() instead nothing is captured. Any ideas how to fix this? char* artist = new char [256]; char * getArtist() { cout << "Enter Artist of CD: " << endl;...

I'm wondering how to implement what is stated in the title. I've tried something like... std::for_each( a.begin(), a.end(), std::mem_fun_ref( &myClass::someFunc ) ) but I get an error saying that the "term" (I"m assuming it means the 3rd argument) doesn't evaluate to a function with 1 argument, even though someFunc does take one argume...
Hiya. I'm using std::getline to read lines from a file, how can I move forward a few lines? do I have to use getline the number of lines I want to skip? thanks! ...
Hello, i have a long string variable and i want to search in it for specific words and limit text according to thoses words.

I'm making a notepad-like program. To get the text from a file I read each character into the buffer by doing while (!file.EOF()) { mystr += file.get(); } however if I load in an exe it stops after MZ but Notepad reads the whole exe. I set my ifstream to binary mode but still no luck. What am I doing wrong? Thanks code: (messy) vo...
Hello, I would like to define inside a class a constant which value is the maximum possible int. Something like this: class A { ... static const int ERROR_VALUE = std::numeric_limits<int>::max(); ... } This declaration fails to compile with the following message: numeric.cpp:8: error: 'std::numeric_limits::max()' cann...
Possible Duplicate: How do I iterate over cin line by line in C++? I need to read all lines from a file: std::ifstream file("..."); std::vector<std::string> svec( (std::istream_iterator<std::string>(file)), (std::istream_iterator<std::string>()), ); but it is read as words. ...
(Note to any future readers: The error, unsurprisingly, is in my code and not std::_Rb_tree_rebalance_for_erase () ) I'm somewhat new to programming and am unsure how to deal with a segmentation fault that appears to be coming from a std function. I hope I'm doing something stupid (i.e., misusing a container), because I have no idea how...
Using type std::string to accept a sentence, for practice (I haven't worked with strings in C++ much) I'm checking if a character is a vowel or not. I got this: for(i = 0; i <= analyse.length(); i++) { if(analyse[i] == 'a' || analyse[i] == 'e' [..etc..]) { ...vowels++; } else { ... ...consonants++; } This works fine if the strin...
Hello! My problem can be described the following way: I have some data which actually is an array and could be represented as char* data with some size I also have some legacy code (function) that takes some abstract std::istream object as a param and uses that stream to retrieve data to operate. So, my question is the following - wha...
I hope the title is describing the problem, i'll change it if anyone has a better idea. I'm storing information in a struct like this: struct AnyStruct { AnyStruct() : testInt(20), testDouble(100.01), testBool1(true), testBool2(false), testBool3(true), testChar('x') {} int testIn...
Hey, what is the best way to concatenate 2 bitsets? For example i've got boost::dynamic_bitset<> test1( std::string("1111") ); boost::dynamic_bitset<> test2( std::string("00") ); they should be concatenated into a thrid Bitset test3 which then holds 111100 Solutions should use boost::dynamic_bitset. If the solution works with st...
I would like to make an std::list of arrays. specifically, I want a list of arrays of Borland Code Builders AnsiStrings. the real kicker being that I would like the arrays to be allocated dynamically. How do I define the list? Im so lost here i dont know were to begin. std::list<???> myList; What am I putting inside the angle brack...
I was under the impression that std::tr1::array was the same as the boost::array in that it would throw an exception when accessing an index out of bounds. In fact, I took a peek in the header and it appears that way as well. Could someone explain why the following code results in a bus error (gcc version 4.0.1 (Apple Inc. build 5465)) ...
It is widely known that adding declarations/definitions to namespace std results in undefined behavior. The only exception to this rule is for template specializations. What about the following "hack"? #include <iostream> namespace std_ { void Foo() { std::clog << "Hello World!" << std::endl; } using namespace std; } int...
We are currently building an API for a certain library. Part of the interface requires the library to get and return to the user classes such as vector and string. When trying to simulate use of the library in a simple scenario, in debug mode the system crush when delivering a string as an input. I believe there is a different represen...
