vector - C++ Users

Aliased as member type vector::value_type. Alloc Type of the allocator object used to define the storage allocation model. By default, the allocator class template is used, which defines the simplest memory allocation model and is value-independent. Aliased as member type vector::allocator_type. Member types

Except for the std::vector<bool> partial specialization, the 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 array.

Fills a vector with multiple values: at() Returns an indexed element from a vector: back() Returns the last element of a vector: begin() Returns an iterator pointing to the beginning of a vector: capacity() Returns the number of elements that a vector's reserved memory is able to store: clear() Removes all of the contents of a vector: data()

std::vector reference | C++ Programming Language

std::vector is a container that encapsulates dynamic size arrays. Memory The elements are stored contiguously, one after another. 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 array.

Vector in C++ STL - GeeksforGeeks

C++ vector is a dynamic array that stores collection of elements same type in ... the vector front() is a built-in function used to retrieve the first element of the vector. It provides a reference to the first element, allowing you to read or modify it directly.Letâ€™s take a quick look at a simple example that uses ...

vector::empty - C++ Reference - cplusplus.com

The example initializes the content of the vector to a sequence of numbers (form 1 to 10). It then pops the elements one by one until it is empty and calculates their sum.

Parameters alloc Allocator object. The container keeps and uses an internal copy of this allocator. Member type allocator_type is the internal allocator type used by the container, defined in vector as an alias of its second template parameter (Alloc). If allocator_type is an instantiation of the default allocator (which has no state), this is not relevant.

vector::emplace_back - C++ Reference - cplusplus.com

Inserts a new element at the end of the vector, right after its current last element.This new element is constructed in place using args as the arguments for its constructor. This effectively increases the container size by one, which causes an automatic reallocation of the allocated storage space if -and only if- the new vector size surpasses the current vector capacity.

vector 的存储是自动处理的，根据需要扩展。 Vectors 通常比静态数组占用更多空间，因为分配了更多内存来处理未来的增长。这样，vector 不需要每次插入元素时都重新分配，而仅在额外内存耗尽时才重新分配。

first, last - the pair of iterators defining the range of elements to sort : policy - the execution policy to use : comp - comparison function object (i.e. an object that satisfies the requirements of Compare) which returns true if the first argument is less than (i.e. is ordered before) the second.. The signature of the comparison function should be equivalent to the following:
