I\'m pondering a current limitation of STL iterators and wondering if there\'s an elegant way around it. Here\'s my situation: I have a class that encapsulates a sequence container and a generic metho
I have this situation: I have a class which keeps track of an array of pointers. I built a custom iterator which loops through this array.
I have a class which uses a HashSet and I want the class implement Iterable, I do not, however, want the class iterator to support the remove() method.
I have a multi-line string defined like this: foo = \"\"\" this is a multi-line string. \"\"\" This string we used as test-input for a parser I am writing. The parser-function receives a file-obje
#include \"stdafx.h\" int _tmain(int argc, _TCHAR* argv[]) { string s = \"Haven\'t got an idea why.\"; auto beg =s.begin();
I can check for a next() m开发者_运维知识库ethod, but is that enough?Is there an ideomatic way?In Python 2.6 or better, the designed-in idiom for such behavioral checks is a \"membership check\" with
In C++, why does string::find return size_type and not an iterator? It would make sense because functions like string::replace or string::insert take iterators as input, s开发者_开发技巧o you could
How can I select a random element in an std::set? I na开发者_运维技巧ively tried this: int GetSample(const std::set<int>& s) {
FYI: no boost, yes it has this, I want to reinvent the wheel ;) Is there some form of a selective iterator (possible) in C++? What I want is to seperate strings like this:
What is the purpose of开发者_如何学C STL iterators? Why have programmers created this concept at all?Iterators allow you to separate algorithms from the container. As long as you have a start and end
