It should exchange the value of the two variable parameters. The two parameters are passed by reference so that swap() can change them and the calling function will see the change.

Most likely its raw definition will be something like this :

void swap(char& a, char& b)
{
   char temp = a;
    a = b;
    b = temp;
}

Think of whats happening.
