Description
count() is used to count occurrences of a value in a sequence of elements.
Declaration
template <class In, class T> iterator_traits<In>::difference_type count(In, In, const T&);
Concept
The sample program sets up a string, and then counts all the a letters within it. A value of 6 is displayed.
Special Notes:
Note that the return type for the count of elements is iterator_traits<T>::difference_type, which captures varying platform-specific size requirements in a portable way.
