| lhs, rhs | - | objects to swap |
[edit] Example
Run this code
#include <any> #include <print> #include <string> int main() { std::any p = 42, q = std::string{"Bishop"}; std::println("p: {}, q: {}", std::any_cast<int>(p), std::any_cast<std::string&>(q)); std::println("swap(p, q)"); std::swap(p, q); std::println("p: {}, q: {}", std::any_cast<std::string&>(p), std::any_cast<int>(q)); }
Output:
p: 42, q: Bishop swap(p, q) p: Bishop, q: 42
