Example

deque<string> cars = {"Volvo", "BMW", "Ford", "Mazda"};
deque<string>::iterator it = cars.begin();
cout << *it;Definition and Usage
The begin() function returns an iterator (an object that points to an element, similar to a pointer). It points to the first element of the deque. Use * to get the value of the element.
begin() is often used together with end() to loop through a deque.
The begin function is defined in the <deque> header file.
