Mutiset STL

hi..
i am facing a prob as shown below



it=find(value) and erase(it) erases both the values(in case of repeating values)... but how do i erase only one of the two values

thanks

Does it?

Code:

---

#include <set>
#include <iostream>
#include <iterator>
#include <algorithm>
using namespace std;

int main()
{
    multiset<int> s;
    s.insert(2);
    s.insert(3);
    s.insert(1);
    s.insert(2);
    copy(s.begin(), s.end(), ostream_iterator<int>(cout, " ")); cout << '\n';
    s.erase(s.find(2));
    copy(s.begin(), s.end(), ostream_iterator<int>(cout, " ")); cout << '\n';
}

no insertion is done in right way..(tat s the neccesity for multiset)
eg:
if i insert
1 2 2 3 3 4 5 6 7 8 8 9
its done
then my requirement is to delte the first occurence of 2

so i need to : find(2)

erase(it)

but when i erase
it is resulting in 1 3 3 4 5 6 7 8 8 9
but the expected outcome is
1 2 3 3 4 5 6 7 8 8 9

You may need to post your code because my code doesn't produce unexpected output.

Code:

---

#include <set>
#include <iostream>
#include <iterator>
#include <algorithm>
using namespace std;

int main()
{
    int arr[] = {1, 2, 2, 3, 3, 4, 5, 6, 7, 8, 8, 9};
    multiset<int> s(arr, arr + sizeof(arr) / sizeof(arr[0]));

    copy(s.begin(), s.end(), ostream_iterator<int>(cout, " ")); cout << '\n';
    s.erase(s.find(2));
    copy(s.begin(), s.end(), ostream_iterator<int>(cout, " ")); cout << '\n';
}
