WebWe could pass pointers to x and y; this way, even if they are copies, they are still valid addresses, and we can effect the swap: void swap(int *px, int *py) { int temp; temp = *px; *px = *py; *py = temp; } main() { int x = 5, y = 6; swap(&x, &y); cout "x = " x ", y = " y; } // Here is another: void returns2(int *px, int *py); main() { int x, y ... WebMar 7, 2024 · The expression (&a + 1) is actually an address just after end of array ( after address of 5 ) because &a contains address of an item of size 5*integer_size and when we do (&a + 1) the pointer is incremented by 5*integer_size. ptr is type-casted to int * so when we do ptr -1, we get address of 5
