Álvaro don't complain go for
temp=a;
a=b;
b=temp;
even objects and structure variables can be swapped with this otherwise need to overload operators

a=a+b-(b=a);

Not advisable, though, if the int numbers are too large, as this could lead to an overflow problem.

#include <iostream>
using namespace std;
int main() {
int a,b;
a=3;
b=5;
cin >> a;
cin >> b;
//swapping without third variable.
a=a+b;
b=a-b;
a=a-b;
cout << a;
cout << " and ";
cout << b;
}

in python:
a, b = b, a
you can't get any better way to swap :)
