Ausnahmen

noexcept specification:  (seit C++11)

noexcept(      noexcept(std::swap(first, p.first)) &&      noexcept(std::swap(second, p.second)) )

Beispiel

#include <iostream>
#include <utility>
#include <string>
int main()
{
    std::pair<int, std::string> p1, p2;
    p1 = std::make_pair(10, "test");
    p2.swap(p1);
    std::cout << "(" << p2.first << ", " << p2.second << ")\n";
}

Output:

(10, test)
