Spletstd::swap is a built in function of C++ Standard Template Library (STL) which swaps two variables, vectors or objects. Syntax : std::swap(a,b) :: is the scope resolution operator in C++. To use swap directly instead of using std, we need to set the namespace std like: using namespace std; swap(a, b); SpletFirst, we will do it manually, and second, we will do using the built-in C++ function that swap () method. Suppose we are given a 1D array such as an array having size 6 and we want to swap two elements having values 1 and 3 so that the array becomes sorted in decreasing order. array [6] = {5,4,1,2,3,0} SpletData races The members of both pair objects, x and y, are modified. Exception safety If both T1 and T2 have a swap function defined and this is noexcept, this function never throws exceptions (no-throw guarantee). Otherwise, if at least one of them swaps with move semantics, the operation may leave either or both pair objects in an invalid state in case … the art of disney book
