There are two differences, which are very much related. The first difference is that cbegin has no overloads, and it is const qualified, while begin is overloaded by two functions one of which is const qualified and the other is not.. The second difference is in the type of the iterator that they return.

As some of the previous posters have stated end() is one past the end element. If you need to access the last element via iterators use iter = container.end() - 1; Otherwise, in the case of vectors, variable = someVector.back(); Assuming that variable is of the data type someVector contains.. In regard to what guarantees that it points to the end, the container itself …

C (programming language)
C (pronounced / ˈ s iː / – like the letter c) [6] is a general-purpose programming language was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C''s features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems code (especially in kernels [7]), device drivers, and protocol stacks, but its …
vector::begin() and vector::end() in C++ STL
The list::end() is a built-in function in C++ STL which is used to get an iterator to past the last element. By past the last element it is meant that the iterator returned by the end() function return an iterator to an element which follows the last element in the list container. It can not be used to modify the element or the list container.

How does C know the end of my string?
Anyway, according to Wikipedia, a string in C is a "Null-terminated string". I always thought this way and everything was good. But the problem is: we put no "null-character" in the end of the non_spaced string. And somehow the compiler knows that it ends at the last character changed by the "non_spaced" string. How does it know?

c++
begin() and end() return iterators. Iterators provide uniform syntax to access different types of containers. At the first glance they might look like an overkill for traversing a simple array, but consider that you could write the same code to traverse a list, or a map.
c++
Actually .end() does not return the iterator to the last element, rather it returns iterator to past-the-last-element.The iterator to the last element is just before it; that is, if it points to the last element, then ++it makes it to point to past-the-last-element.. The language specification calls it past-the-end iterator. §24.1/5 (C++03) reads, Just as a regular pointer to …
