Another stuct problme

struct b{//elements};

struct b* funcfoo(){
struct b* p={0};
//do something with p
return p;
}
int main(){
struct b*p=//call funcfoo
printf(*%d%s*,p->inte,p->str);
return 0;
}

I am sure you know why ? This is a reapeated error I wasn't able to
memorize. It's on others next to me not me anyway, hehe. Thanx

What you've shown us is not compilable code, so it doesn't segfault.

Guessing wildly at a fix, I'd say that someone has tried to dereference
a null pointer. Bad dog. Null biscuit.

It depends on what you do with p. Unless you assign a different value
to p (such as by using malloc), the printf in main will always yield
undefined behavior. In this case, you are lucky that this particular
type of undefined behavior yields a segmentation fault.

return p;
}
int main(){
struct b*p=//call funcfoo
printf(*%d%s*,p->inte,p->str);
return 0;
}
