1. char * PrintMe() {
char str[12];
strncpy (str, "hello world", 11);
str[11] = 0;
return str;
}

2. struct my_struct { int val; };
int my_func( struct my_struct *ptr, int x, int y) {
int z = 0;
if((ptr != NULL) && (x < y) || (ptr->val > 0)) {
z = x + y - ptr->val;
}
return z;
}

3. class Base {
public:
int x;
};

class Derived : public Base {
public:
int y;
};

void init(Base *b) {
for( int i = 0; i < 3; ++i) {
b[i].x = 0;
}
}

void foo() {
Derived arr[3];
init(arr);
}
