See the following code:

<code>
#include <iostream>
using namespace std;


void swapvars( int a, int b ) {
    int temp = a;
    a = b;    // a is now b
    b = temp; // b is now a
}


int main ()
{
   int a = 2;
   int b = 3;
   
   swapvars( a, b );
   
   cout << "The value of a is " << a << " and the value of b is " << b;
   
   return 0;
}

</code>

What will be output by the above program?
  * a - The value of a is 2 and the value of b is 3;
  * b - The value of a is 3 and the value of b is 2;
  * c - The value of a is 2 and the value of b is 2;
  * d - The value of a is 3 and the value of b is 3;

<poll What will be output by the above program? [c]>
  * a
  * b
  * c
  * d
</poll>
