multiset::lower_bound (STL/CLR)

Finds beginning of range that matches a specified key.

    iterator lower_bound(key_type key);

Parameters

  • key
    Key value to search for.

Remarks

The member function determines the first element X in the controlled sequence that has equivalent ordering to key. If no such element exists, it returns multiset::end (STL/CLR)(); otherwise it returns an iterator that designates X. You use it to locate the beginning of a sequence of elements currently in the controlled sequence that match a specified key.

Example

// cliext_multiset_lower_bound.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(); 
 
    System::Console::WriteLine("lower_bound(L'x')==end() = {0}", 
        c1.lower_bound(L'x') == c1.end()); 
 
    System::Console::WriteLine("*lower_bound(L'a') = {0}", 
        *c1.lower_bound(L'a')); 
    System::Console::WriteLine("*lower_bound(L'b') = {0}", 
        *c1.lower_bound(L'b')); 
    return (0); 
    } 
 
 a b c
lower_bound(L'x')==end() = True
*lower_bound(L'a') = a
*lower_bound(L'b') = b
