Do not create third-party variables for integer array inversion

Using an integer array as an example to implement the inverse

Reverse an integer array, such as Array a[5]={1,2,3,4,5}, after which the contents of array a become {5,4,3,2,1}.

void Swapnum (int& A, int& b) {a = A^b; b = a^b; a = a^b;} void Swaparray (int *str,int size) {int i = 0; for (i = 0; i < SIZE/2; i++) {Swapnum (str[i], str[size-i-1]);}} void Test () {int arr[5] = {1, 2, 3, 4, 5}; int size = sizeof (arr)/sizeof (arr[0]); Swaparray (arr,size); int i = 0; while (i<size) {printf ("%d", arr[i++]);}}
