在Boost库中,数值范围迭代器可以通过使用boost::counting_iterator来实现。boost::counting_iterator是一个模板类,它接受一个类型参数,该参数表示要生成的数值的类型。例如,如果要生成一系列的整数,则可以使用以下代码: 代码语言:cpp 复制 #include<boost/iterator/counting_iterator.hpp
counting_iterator_test.cpp(113): test 'std::distance(x, y) == 1' failed in function 'void __cdecl category_test<class boost::iterators::counting_iterator<class std::_Vector_iterator<class std::_Vector_val<struct std::_Simple_types<int> > >,struct boost::use_default,...
1简介编辑 shared_ptr是一种智能指针(smart pointer)。 2作用编辑 shared_ptr的作用有如同指针,但会记录有多少个shared_ptrs共同指向一个对象。这便是所谓的引用计数(reference counting)。一旦最后一个这样的指针被销毁,也就是一旦某个对象的引用计数变为0,这个对象会被自动删除。这在非环形数据结构中防止资源泄露...
tokenized 可以利用一个 regular expression 将对应容器里的“字符”组织成为 token,作用和 regex_token_iterator 是一样的; transformed(fun) 将利用 fun 进行转换获得新的值; uniqued 将进行去重(de-dup) 提供的 range 类型有 any_range、counting_range、istream_range 与 irange(整数类型的)。提供的算法与 S...
