set::upper_bound (STL/CLR)
Finds end of range that matches a specified key.
iterator upper_bound(key_type key);
Parameters
- key
Key value to search for.
Remarks
The member function determines the last element X in the controlled sequence that has equivalent ordering to key. If no such element exists, or if X is the last element in the controlled sequence, it returns set::end (STL/CLR)(); otherwise it returns an iterator that designates the first element beyond X. You use it to locate the end of a sequence of elements currently in the controlled sequence that match a specified key.
Example
// cliext_set_upper_bound.cpp
// compile with: /clr
#include <cliext/set>
typedef cliext::set<wchar_t> Myset;
int main()
{
Myset 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("upper_bound(L'x')==end() = {0}",
c1.upper_bound(L'x') == c1.end());
System::Console::WriteLine("*upper_bound(L'a') = {0}",
*c1.upper_bound(L'a'));
System::Console::WriteLine("*upper_bound(L'b') = {0}",
*c1.upper_bound(L'b'));
return (0);
}
a b c upper_bound(L'x')==end() = True *upper_bound(L'a') = b *upper_bound(L'b') = c
