C++ 指標的偏移 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};
