Vector less than comparison.
template<typename Value>
bool operator<(vector<Value>% left,
vector<Value>% 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->size() < right->size() You use it to test whether left is ordered before right when the two vectors are compared element by element.
Example
// cliext_vector_operator_lt.cpp
// compile with: /clr
#include <cliext/vector>
int main()
{
cliext::vector<wchar_t> c1;
c1.push_back(L'a');
c1.push_back(L'b');
c1.push_back(L'c');
// display contents " a b c"
for each (wchar_t elem in c1)
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
// assign to a new container
cliext::vector<wchar_t> c2;
c2.push_back(L'a');
c2.push_back(L'b');
c2.push_back(L'd');
// display contents " a b d"
for each (wchar_t elem in c2)
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
