Exactly, that’s what I am confused about too. Swapping the pointers is not same as swapping the value at pointed address.

If i and j are two variables, then the expression for swapping their values will be
i=i+j-(i+j);

a=2,b=5;
a=(a+b)-(b=a);

If x and y are pointers to the same value, then you’re only ‘swapping’ one thing, which is nonsensical?? It’s like say I’m going to swap 1.
