how do i change the fuction below using pointer method to return back the value of x and y?
Code:void exchange(int x,int y) { int temp; temp = x; x = y; y = temp; return ; }

You would change the parameters x and y such that they are pointers to int rather than int variables. Then you make the corresponding changes to the implementation of the function.

Call the function like this exchange(&a,&b).Code:void exchange(int *x,int *y) { int temp; temp = *x; *x = *y; *y = temp; }
