A lot of languages use braces to structure code. But in C++, braces are much more than mortar for holding blocks of code together. In C++, braces have meaning. Or more exactly, braces have several meanings. Here are 5 simple ways you can benefit from them to make your code more expressive. #1 Filling all sorts of containers Before C++11, putting initial contents in an STL was a pain: std::vector<s
The Standard Template Library (STL) is a library for the C++ programming language. The STL provides many useful algorithms and containers. The Containers are objects that store data. We have taken the help of the following containers to solve mentioned problems: vector, list, queue, priority_queue, stack, set, map, multimap, unordered_set, unordered_multiset, unordered_map, unordered_multimap We h
やあ子供たち。今日はSTLのstd::⇒ vector, list, set, dequeのパフォーマンス測定の実験をしたよ。以下のようなコードだ。試してみてくれ。 #include <iostream> #include <vector> #include <list> #include <algorithm> #include <ctime> #include <set> #include <deque> using namespace std; #define N 1000000 #define P 400000 class less_than_4000 { public: bool operator()( int i ){ return i<P; } }; int main( int argc, char* argv[] ) { vector< int > vec; list< i
