comparison operators

function

template <class T, class Container>
  bool operator== ( const stack<T,Container>& x, const stack<T,Container>& y );
template <class T, class Container>
  bool operator< ( const stack<T,Container>& x, const stack<T,Container>& y );

template <class T, class Container>

  bool operator<= ( const stack<T,Container>& x, const stack<T,Container>& y );

Global comparison operator functions

These overloaded global operator functions perform the appropriate comparison operation between stack container adaptors x and y.

Operations == and != are performed by comparing the elements using algorithm equal.

Operations <, >, <= and >= are performed by using algorithm lexicographical_compare, which requires that the type of the elements (T) has the < operation (less-than) defined between two objects of that type.

These operators are overloaded in header <stack>.

Parameters

x, y: stack container adaptors, having both the same template parameters (T and Container).

Return Value

true if the condition holds, and false otherwise.
