|   void swap( stack& other ) noexcept(/* see below */);  | 
(since C++11) | |
Exchanges the contents of the container adaptor with those of other. Effectively calls using std::swap; swap(c, other.c);
Parameters
| other | - | container adaptor to exchange the contents with | 
Return value
(none)
Exceptions
| 
 noexcept specification:  
 
noexcept(noexcept(swap(c, other.c))) In the expression above, the identifier   | 
(until C++17) | 
| 
 noexcept specification:  
 
noexcept(std::is_nothrow_swappable<Container>::value)  | 
(since C++17) | 
Complexity
Same as underlying container (typically constant)
