// Scala program to swap adjacent elements // in the array object Sample { def main(args: Array[String]) { var IntArray = Array(10, 20, 30, 40, 50, 60) var i: Int = 0 var t: Int = 0 //swap adjacent elements while (i < 6) { t = IntArray(i); IntArray(i) = Int...
In the below example, we see how to swap two integers usingstd::swap()function. #include <bits/stdc++.h>usingnamespacestd;intmain() {inta=10, b=20; cout<<"Before swapping:\n"; cout<<"a: "<<a<<", b: "<<b<<endl;//swap nowswap(a, b); cout<<"After swapping:\n"; cout...
Forward iterators to the initial and final positions in one of the sequences to be swapped. The range used is [first1,last1), which contains all the elements between first1 and last1, including the element pointed by first1 but not the element pointed by last1. first2 Forward iterator ...
After the call to this member function, the elements in x are those which were in y before the call, and the elements of y are those which were in x. All iterators, references and pointers remain valid for the swapped objects. This is an overload of the generic algorithm swap that imp...
