This outputs ----> 3 4
-which is correct but i would like to know how to swap elements to, say, make the output 4 3.

p.s. example.swap(3,4) //Error (swap takes 1 arg)

CODE:

#include <iostream.h>
#include <vector>
using namespace std;

int main()
{
vector <int> example;

example.push_back(3);
example.push_back(4);


for(int y=0; y<example.size(); y++)
cout<<example[y]<<" ";

cout<<endl;
return 0;
}
