Question

Consider the following C function

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

In order to exchange the values of two variables x and y.

a.

Call swap (x, y)

b.

Call swap (&x, &y)

c.

swap(x,y) cannot be used as it does not return any value

d.

swap(x,y) cannot be used as the parameters are passed by value

Answer: (d).swap(x,y) cannot be used as the parameters are passed by value
