Eccezioni

noexcept specification:  (dal C++11)

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

Esempio

#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)
