B20: problem in C++ pointer

[swe sd]

   I compiled the following program (attachment test.cc):
     line 1:  #include <iostream>
     line 2:  void main()
     line 3:  { const int size=10;
     line 4:    int A[size];
     line 5:    int *X=NULL, i;
     line 6:    for (i=0;i<size;i++) A[i]=i;
     line 7:    cout<<A[0]<<" "<<&A<<" "<<&A[0]<<endl;
     line 8:    X=A;
     line 9:    cout<<A[0]<<" "<<&A<<" "<<&A[0]<<endl
     line 10:       <<*X<<endl
     line 11:       <<*X+5<<endl
     line 12:       <<*X<<" "<<A[0]<<endl
     line 13:       <<5+X[0]<<endl
     line 14:       <<( X[0]==0 ? "X[0]=0" : "X[0]!=0")<<endl
     line 15:       <<++X[0]<<endl
     line 16: }
    and executing it gives output:
           $./a.out
           0 0x259fd7c 0x259fd7c
           1 0x259fd7c 0x259fd7c
           1
           6
           1 1
           6
           X[0]!=0
           1
    Obviously, the output of line 9 is different from line 7 which should be 
the same indeed. Is there anything wrong ? Thanks.
