This C code fragment is run: { x = 38; y = 45; int int int z; z = x ^ y; z ^= X; The final value of z is: 45 38 7 -7

c++ coding language   I need help with part B and C please. If you are unable to do both, then PLEASE prioritize part C. I am really stuck and really can use the help.       This is the code for c that was provided in order to guide me: const int N =31;    // N parking spaces bool parking[N];   // the garage   void EmptyTheLot(bool parking[], int N) {    for(int i=0; i<N; i++) p[i]=false;       // empty space }   // returns -1 if no space found,  //otherwise it returns   0<=i<N for a valid space.  int FindSpace(int PlateNumber, bool parking[], int N) {       // ?????                                    }    main() {  EmptyTheLot(parking, N);    // start with an empty parking garage. // get plate numbers and fill lot.  }

Look at the following C++ code and comment each line about how it works with pointer. int i = 33; double d = 12.88; int * iPtr = &i;      double * dPtr = &d; //   iPtr = &d;   //   dPtr = &i;   //   iPtr = i;    //     int j = 99; iPtr = &j;  //
