operator< function template — Compares for less-than
template <typename T, typename A> bool operator<(const vector<T,A>& x, const vector<T,A>& y); template <typename Alloc> bool operator<(const vector<bool,Alloc>& x, const vector<bool,Alloc>& y);
The <
operator
determines whether x
is less than
y
using the same algorithm as
lexicographical_compare(x.begin(
)
, x.end( )
, y.begin( )
, y.end( ))
.
