C++ 指针的偏移 The offset of a pointer in C++
A problem from my friend, what‘s the result of the following code:
class str{ public: int x; char s[0]; }; class foo{ public: str * p; }; int main() { foo f = {0}; str* p1 = NULL; if (f.p->s){ printf("%d\n", f.p->s); } return 0; }
This sentence sets p to NULL:
foo f = {0};
