What is a vector in CPP? A vector in CPP is used to implement a dynamic array. Vector in real, is a sequence container class. Here, dynamic array means that the array size automatically resizes itself when appending elements at run time. However, in static array, array size cannot be changed during run time. To provide a reference to an element.
What is a vector bool reference class? The vector reference class is a nested class whose objects can provide references to elements (single bits) within a vector object. Constructs a vector of a specific size or with elements of a specific value or with a specific allocator or as a copy of some other vector. A type that represents the allocator class for the vector object.
What is a vector container? The vector container, declared in , allows for keeping a variable sequence of elements of arbitrary data type. These are its essential properties: The data type of the elements in the vector can be defined as a template argument: Vectors have a variable number of elements, which can be inserted, removed and accessed in runtime:
What is the function pointing to the first element in a vector? Returns an iterator pointing to the first element in the vector. Notice that, unlike member vector::front, which returns a reference to the first element, this function returns a random access iterator pointing to it. If the container is empty, the returned iterator value shall not be dereferenced.
