WebC++ Structures. Structures (also called structs) are a way to group several related variables into one place. Each variable in the structure is known as a member of the structure. Unlike an array, a structure can contain many different data types (int, string, bool, etc.). WebReturns an iterator pointing to the first element in the array container. Notice that, unlike member array::front, which returns a reference to the first element, this function returns a random access iterator pointing to it. In zero-sized arrays, this function returns the same as array::end, but the returned iterator should not be dereferenced. ...
