Thevalarray class in C++is a special container that is used for holding elements like an array and performing operations on them. C++ STL std::swap (valarray) Function Theswap()function is defined invalarrayclass, and it is used to swap the content of onevalarraywith anothervalarray. ...
C++ STL std::swap() Function swap()is a standard library function that swaps the value b/w any two objects. In C11, it has been moved under<utility>header. Below is the syntax details forswap(). Syntax void swap (T& a, T& b); ...
In the following example, we are going to consider the basic usage of the swap() function.Open Compiler #include <iostream> #include <array> int main() { std::array < int, 3 > x = {1,3,5}; std::array < int, 3 > y = {2,4,6}; x.swap(y); std::cout << "\n\nAfter...
constexprvoidswap(array<T,N>&lhs, array<T,N>&rhs)noexcept(/* see below */); (C++20 起) 为std::array特化std::swap算法。交换lhs与rhs的内容。调用lhs.swap(rhs)。 此重载仅若N == 0或std::is_swappable<T>::value为true才参与重载决议。
other-要与之交换内容的array 返回值 (无) 异常 noexcept规定: noexcept(noexcept(swap(std::declval<T&>(),std::declval<T&>())) 在以上表达式中,按照同 C++17std::is_nothrow_swappable特性所用的行为查找标识符swap。 (C++17 前) noexcept规定: noexcept...

This function swaps two items in an array based on their indices. JavaScript: let swapItems = (arr, i, j) => ([arr[i], arr[j]] = [arr[j], arr[i]], arr); // Example console.log(swapItems(['a', 'b', 'c', 'd', 'e'], 1, 3)); // ['a', 'd', 'c', 'b'...
