The latest version of this topic can be found at multiset::insert (STL/CLR).

Adds elements.

Syntax

iterator insert(value_type val);  
iterator insert(iterator where, value_type val);  
template<typename InIter>  
    void insert(InIter first, InIter last);  
void insert(System::Collections::Generic::IEnumerable<value_type>^ right);  

Parameters

first
Beginning of range to insert.

last
End of range to insert.

right
Enumeration to insert.

val
Key value to insert.

where
Where in container to insert (hint only).

Remarks

Each of the member functions inserts a sequence specified by the remaining operands.

The first member function inserts an element with value val, and returns an iterator that designates the newly inserted element. You use it to insert a single element.

The second member function inserts an element with value val, using where as a hint (to improve performance), and returns an iterator that designates the newly inserted element. You use it to insert a single element which might be adjacent to an element you know.

The third member function inserts the sequence [``first``, last``). You use it to insert zero or more elements copied from another sequence.

The fourth member function inserts the sequence designated by the right. You use it to insert a sequence described by an enumerator.

Each element insertion takes time proportional to the logarithm of the number of elements in the controlled sequence. Insertion can occur in amortized constant time, however, given a hint that designates an element adjacent to the insertion point.

Example

// cliext_multiset_insert.cpp   
// compile with: /clr   
#include <cliext/set>   
  
typedef cliext::multiset<wchar_t> Mymultiset;   
int main()   
    {   
    Mymultiset c1;   
    c1.insert(L'a');   
    c1.insert(L'b');   
    c1.insert(L'c');   
  
// display initial contents " a b c"   
    for each (wchar_t elem in c1)   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
  
// insert a single value, unique and duplicate   
    System::Console::WriteLine("insert(L'x') = {0}",   
        *c1.insert(L'x'));   
  
    System::Console::WriteLine("insert(L'b') = {0}",   
        *c1.insert(L'b'));   
  
    for each (wchar_t elem in c1)   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
  
// insert a single value with hint   
    System::Console::WriteLine("insert(begin(), L'y') = {0}",   
        *c1.insert(c1.begin(), L'y'));   
    for each (wchar_t elem in c1)   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
  
// insert an iterator range   
    Mymultiset c2;   
    Mymultiset::iterator it = c1.end();   
    c2.insert(c1.begin(), --it);   
    for each (wchar_t elem in c2)   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
  
// insert an enumeration   
    Mymultiset c3;   
    c3.insert(   // NOTE: cast is not needed   
        (System::Collections::Generic::IEnumerable<wchar_t>^)%c1);   
    for each (wchar_t elem in c3)   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
    return (0);   
    }  
  
 a b c  
insert
(L'x') = x  
insert
(L'b') = b  
 a b b c x  
insert
(begin(), L'y') = y  
 a b b c x y  
 a b b c x  
 a b b c x y
