Vector is a very useful container in C ++. Vector is considered a container because it can store various types of objects like a container. Simply put, vector can be of any type (int, double, string, can also be

N, there is a channel connection between some passes. Among them, the Legion was in the 1th, and the Scourge was in the N. One day, the leader of the Scourge, the Lic
Vector is a common container in the C + + Standard Template Library, like arrays, vectors use contiguous storage space to hold elements, using pointer offsets to quickly access elements (often considered O1 complexity), unlike arrays where the size is variable, Using dynamically allocated memory to hold elements inside the vector means that the
In C + +, vector is a very useful container, and here is a summary of the container. 1 Basic operations (1) header file #include (2) Create vector object,vector (3) Insert number at tail: vec.push_back (a); (4) Use subscript to access the element,cout (5) Use iterators to access elements. Vector (6) Insert element: Vec
