Given below are three implementations of the swap function:

a. void swap (int a, int b)

{

int temp;

temp = a;

a = b;

b = temp;

}

int main ()

{

int i = 0,

j = 1;

swap (i, j);

}

b. void swap (int &a, int &b)

{

int temp;

temp = a;

a = b;

b = temp;

}

int main ( )

{

int i = 0,

j = 1;

swap (i, j);

}

3. void swap (int *a, int *b)

{

int *temp;

temp = a;

a = b;

b = temp;

}

int main ( )

{

int i = 0,

j = 1;

swap (&i, &j);

}

Which of these would actually swap the contents of the two integers i and j ?

A. a only

B. b only

C. c only

D. a and b only 6.

E. b and c only
