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.
