swap_int

Your mission

Implement a function that exchanges the values stored at two integer addresses.

See it in action

int x = 7, y = 99; swap_int(&x, &y);

Expected result

x = 99, y = 7

Your checklist

For your own tracking. Tests grade your code.

The function takes two pointers to integers as parameters.
After the call, each pointer must point to the value the other held before.
Use a local temporary variable to perform the exchange.
Do not dereference any pointer more than necessary.

More examples

int x = 0, y = -3; swap_int(&x, &y);

Expected result

x = -3, y = 0
