std::vector<int>v1;// a vector of integersstd::vector<int*>v2;// a vector of pointers to integer(s)std::vector<std::string>v3;// a vector of stringsstd::vector<std::vector<int>>v3;// a vector of vectors of int's
std::vector<std::unique_ptr<Base>> source; source.push_back(std::make_unique<Derived>()); std::vector<std::unique_ptr<Base>> destination; std::move(begin(source),end(source),std::back_inserter(destination)); 之后,destination拥有了元素,source不为空,而是拥有一堆空的unique_ptr。
Delphi method pointers which make the event treatment by delegation possible are reproduced also for other compilers than the C++ Builder now. There is the language expansion for it in the C++ Builder with the "__closure" keyword. There is a SmallString class for Visual C++ and other compilers...
autoptr1 = make_shared<vector<int>>(10,-1);autoptr2 = make_shared<vector<int>>(vector<int>(10,-1)); 与通过构造函数初始化不同的是,make_shared允许传入一个临时对象,如以下代码: intmain(){ vector<int> v = {1,2,3};autoptr = make_shared<vector<int>>(v);// &v = 0x7ffeef698...
elements are stored contiguously, which means that elements can be accessed not only through iterators, but also using offsets to regular pointers to elements. This means that a pointer to an element of a vector may be passed to any function that expects a pointer to an element of an ...
