operator< (queue) (STL/CLR)
The latest version of this topic can be found at operator< (queue) (STL/CLR).
Queue less than comparison.
Syntax
template<typename Value,
typename Container>
bool operator<(queue<Value, Container>% left,
queue<Value, Container>% right);
Parameters
left
Left container to compare.
right
Right container to compare.
Remarks
The operator function returns true if, for the lowest position i
for which !(``right``[i] <
left``[i])
it is also true that left``[i] <
right``[i]
. Otherwise, it returns left``->
queue::size (STL/CLR)() <
right``->size()
You use it to test whether left
is ordered before right
when the two queues are compared element by element.
Example
// cliext_queue_operator_lt.cpp
// compile with: /clr
#include <cliext/queue>
typedef cliext::queue<wchar_t> Myqueue;
int main()
{
Myqueue c1;
c1.push(L'a');
c1.push(L'b');
c1.push(L'c');
// display contents " a b c"
for each (wchar_t elem in c1.get_container())
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
// assign to a new container
Myqueue c2;
c2.push(L'a');
c2.push(L'b');
c2.push(L'd');
// display contents " a b d"
for each (wchar_t elem in c2.get_container())
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
System::Console::WriteLine("[a b c] < [a b c] is {0}",
c1 < c1);
System::Console::WriteLine("[a b c] < [a b d] is {0}",
c1 < c2);
return (0);
}
a b c
a b d
[a b c] < [a b c] is False
[a b c] < [a b d] is True
