int a{}, b{}, temp{};
cin >> a >> b;

  //===================== METHOD-1
   temp = a;
   a = b;
   b = temp;

  //===================== METHOD-2 ( XOR ^ )
  // example: a^b =  5^7
   a = a ^ b;   // 5^7
   b = a ^ b;   // 5 ^ 7 ^ 7  //5 ( 7 & 7 dismissed)
   a = a ^ b;   // 5 ^ 7 ^ 5  //7 ( 5 & 5 dismissed)

  //===================== METHOD-3  ( swap() )
  swap(a, b);

  cout << "a " << a << endl;
  cout << "b " << b << endl;

C++ set swap

Comment

Input  : set1 = {1, 2, 3, 4}
         set2 = {5, 6, 7, 8}
         set1.swap(set2);
Output : set1 = {5, 6, 7, 8}
         set2 = {1, 2, 3, 4}

Input  : set1 = {'a', 'b', 'c', 'd'}
         set2 = {'w', 'x', 'y', 'z'}
         set1.swap(set2);
Output : set1 = {'w', 'x', 'y', 'z'}
         set2 = {'a', 'b', 'c', 'd'}
