WebIf you want 'C' array performance, but with added safety and STL-like semantics (iterators, begin () & end () etc), use boost::array. Basically it's a templated wrapper for 'C'-arrays with some NDEBUG -disable-able range checking asserts (and also some std::range_error exception-throwing accessors). I use stuff like WebThe C++ STL Douglas C. Schmidt STL Features: Containers, Iterators, & Algorithms • Containers – Sequential: vector, deque, list – Associative: set, multiset, map, multimap – Adapters: stack, queue, priority queue • Iterators – Input, output, forward, bidirectional, & random access – Each container declares a trait for the type of iterator it provides http://www.maxgcoding.com/representing-graphs-with-the-c-stl/ phil schilling

WebThe std::all_of () function is a STL Algorithm in C++. It can be used to check if all the elements of a sequence satisfies a condition or not. The sequence can be a vector, array, list or any other sequential container. We need to include the header file to use the std::all_of () function. WebStandard C++ includes the standard library commonly known as the STL. Every implementation of standard C++ includes the standard library. As such, it doesn’t make sense to remove the standard library from C++. The days of building in utility functions into the language proper are long gone.
