The unordered_multiset::count() is a built-in function in C++ STL which returns the count of elements in the unordered_multiset container which is equal to a given value.
Parameters: The function accepts a single mandatory parameter val which specifies the element whose count in the unordered_multiset container is to be returned.
Return Value: It returns an unsigned integral type which denotes the number of times a value occurs in the container.
Below programs illustrates the above function:
11 occurs 3 times 12 occurs 2 times 13 occurs 2 times 14 occurs 1 times
a occurs 3 times b occurs 2 times c occurs 2 times
