operator== function template — Compares for equality
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 returns
true if x
and y
have the same size and their elements
are equal, that is, x.size() == y.size()
&& equals(x.begin(), x.end(), y.begin( ))
.
