C++ Comparison, What is the outcome? -

-

there simple code 

int a( int *p0 ) {         int p;         if( p0 ) return p0 > &p;         return a(&p); }  int main() {         puts( a(0) ? "y" : "n" ); }

what result , how many times method a called?

comparing pointers using > unspecified if not part of same array.

so there no actual answer, although can assume if stack grows down if( p0 ) return p0 > &p; true, otherwise false.
